Firstly, when making a business remember the important things.

1. When you are open, for use when we have the Calendar implemented.
2. What you sell. Prices. Images perhaps.
3. Staff and if you are hiring. Also if you are going to 'pay' your staff a wage.
4. RPing in businesses is allowed, so dont get shitty.
5. Make sure when someone puts in an order, you place the items in their bank account. If someone doesnt have a bank account then they are really lost arent they?
6. Yes, you may have a seperate bank account for your business. Think about that now.
7. Reserve a few posts at the end.
8. Places like the Inn, Restaurant, Library, and other such places can choose to sell or trade, whatever, and you can also offer other servcices, ie The Inn, have rates for accomodation and meals, Library, have book sales prices, or a book borrowing system. Think it all through.
