I wasn't really thinking about this as a way to make money for the MC, but it could work like the bar, with requiring upgrades to make it more and more profitable.I like it! I hope we can sell them for more than $5 a piece.
First you have to set up the web site, small investment.
Then you have to buy the building. Big one. Or find a rundown one close by that can be fixed up. Medium investment.
Upgrade the building, large investment.
Buy elves 1-X as Nia/Sui finds them. Moderate investment each.
The web site will generate a small income, since most of the money gets reinvested into materials.
Buying and fixing up the building will give a small boost, but that won't really help a lot until the other elves are bought, since the better work area only gets you do far without the people to do the work.
Each new worker needs to be trained, and will slowly help increase the profits up to a point.
