I think the photo studio is completely skipable at starting the business. It isn't necessary to have at beginning, didn't bring passive income, and didn't helping much in the raising fames of the girls like if you put on a marketers advertising on them while they camming. But generate costs and expenses and require a director (and staff), a good equipment and very good models to be able to do work orders (you can get painful penalties for doing low quality work orders). So this shouldn't be priority here, only get when affordable to your budget. IMO alternatively if you have 5k surplus starting with a studioroom, putting existing equipment there, hiring the worst director, and doing upcoming shooting there manually. This way you get rid of amateur video penalty on videos, and scheluding solos for the cheapest models likely makes some profit even publishing on porntube too.You gonna need 10k for office, 5k for photoshoot, so i would say, try to keep having 10k in reserve, keep buying stuff when you won't go below that. I prefer to use as good equipment in photo studio as i can afford, preferably 80 or 100 quality, so i can reliably do photo work contracts. I would say about 60-70k?, you can get loan though, rest is kinda RNG, but consider such approach:
- train your inteligence and fitness, get laptop from store
- use that to get some cheap prostitutes, do a bit porn with them, so you have spare money, use distributor contracts for max money, fans don't matter that much at this point yet,
- get as much special characters you can, especially those 3 from last post, also blonde in the bar, both from the beach, gym girl too, put them all into photoshot, DON'T DO PORN with them yet, so they slowly get fame and do scenes with prostitutes in meantime
- if you already have photo shot and few special characters, get 50k loan for 2 months, it will allow to buy good camera and lighting for your photo studio, get some cheap director (doesn't matter, really, lvl 1 is ok for now) and marketer
- keep repeating scenes with prostitutes and work contracts for photos, events and if possible, anonymous porn requests (ignore geo requests for now) until those 3 mentioned in post above have like 20 fame and you have 2 stars reputation
- get admin, start cams, put your lvl 2 models into cams, keep grinding until you can afford contracts for your camgirls or until you pay first loan, take next loan, give them contracts, with contracts they'll be working for 25+ days a month
- get a few PA so you can get some related bonuses
- profit
That's how it looks for me usually, whether to take loan or not, depends on rng from contracts, you can as well keep it easy and not take loan at all, just give yourself more time. Just don't do porn with those you put into photo studio or cams, you will do much later on, when they're famous, or not, make them GFs or whatever, your call. With that, you should be able to have cams set and running in ~3 months, depends on RNG really.
And just a note, again, don't rush into porn, especially with special characters, porn far is more profitable when you have profesional studio with high end staff, equipment and famous girls. Though it's required early on, just think about it that it's necessity, you just want to get some money to start photo/cams, that will cover you day-to-day operation for few months, with surplus money allowing you to expand into professional porn. Also you need a lot of fans for it to be worth it.
Also, if you find random girls with Blue Balls perk, they're a good candidate for forever camgirl too.

For me the photostudio means a pool of girls with high appearances and almost zero likeliness to do other things or doesn't fit in any other position, but there can gain some fans passively.
And two important thing is missing from your useful summary: if you hasn't a really reason with them (like having high potential) it isn't really worth using girls with low beauty to photoshoot, and with low beauty and sex skill to camshow (they just wasting resources for almost nothing in return). Secondly the advertising the key how fast you can earn money, fame and reputation, and how much. (Keeping webaddmins efficiency and camshows advertising near 100% brings the max profit out from this, makes camgirls more famous and happier too what means they will work more and earn more)
Also taking out loan is dangerous in this stage (opening the company), advised to do more work orders instead if you really need some surplus cash in your hand (IMO). If you can afford advertising a littlebit on company also can helps to get more and accomplishable orders with a little better payouts and/or conditions.
