Yea, I found that, it's ok money but very click intensive. Not sure if I really want to do Cure wounds spamming while my character only sleeps 2 nights a week or something, just feels very gamey. Was hoping that there'd be some stuff for after school finished that payed as well as the stuff you can do from day 1.
The best job in my opinion is the online cam job. You have to invest some money (40k for pc, 2k for webcam, a few internet hours + several k for dildos; maybe worth mentioning that the computer nerd has a pc from game start) and you have to have a low inhibition. In addition it doesn't hurt when Sveta somewhat "stretched". About 6 hours bring 10k - up to 20k in money. I think, a good stat in erotic dancing also helps somewhat, but i could be wrong.
The advantage is, that in addition to the high income, the working hours are flexible, even though it's better to work several hours in a row. Especially as succubus, when you hardly need any sleep, you can spend the nights in front of the pc.
The second best job you can get, is from Arthur at the market place in Pavlovsk. It needs some building up and best is started as soon as possible if you want to have this as main source of income. You have to meet him once, then it is easer to meet him again. When you go with him, he gives you some rewards, like cosmetics or 1k in cash. A second visit on the same day gives 0.50k. When you have done it several times, you can trade for him at the weekend (around 12am), which gives 5k for about 5 hours. After a while he will ask you to work for him every day at 4 pm. This gives 10k and only a few working hours needed.
The other good ones, like the highway hotel, already have been mentioned.
For the highway hotel job and the online cam job, it is nice to have the cure wound spell or be a level 4 succubus.
The highway job is in my opinion best at gamestart to get fast cash. But it get's boring pretty fast and you need a lot of healing. Therefore best done at weekends or during holidays.
Another option to get a little cash at the beginning is by giving bj at the community center and at the weekend at the disco in the city.
Not exactly cash, but it helps to save cash is stealing lots of cosmetics in the mall in the city center. That's usually one of the first things i do in the first few weeks of the game start.
