It definitely won't be easy, I'd recommend you find a business filterscript or a tutorial so you know how to do it. You'd have to create a loading file, probably .cfg which contains all the coordinates etc. for the system, like the biz name, what they do, the level, price and other values you might want to have.

That's why I think you should just get a filterscript to start off with an then edit it to your personal needs.
