That's my really old tutorial (Mid 2010). I'll remake it in a few weeks, currently I have exams. The way you create businesses is like this:

pawn Code:

CreateBusiness(BusinessName[], Float:XPos, Float:YPos, Float:ZPos, Price, Sell, Earn)
/*
BusinessName - The business name
XPos - The X position of the business.
YPos - The Y position of the business.
ZPos - The Z position of the business
price - Cost price of the business
sell - Sell price of the business
earn - The cash you earn from the business
*/

You need to put that on OnFilterScriptInit or OnGameModeInit.
