Well this is a bigger hurdle than you might think (finding a suitable location and finding funding). Before you can apply for funding you need to write a formal business plan. To do that you need to get good solid numbers. Would you need to build a new place or can you find an existing location that could be converted? Figure your costs for a build out. Find out about zoning issues for a drive through. Figure the start up costs:

building cost
racking/equipment
POS system (point of sale)
permits/licenses
professional services (lawyer; accountant)
marketing/advertising
signage
inventory
supplies

Then figure your ongoing expenses:

utilities
taxes
payroll
taxes
advertising
taxes
bank fees
taxes
inventory
taxes

I don't mean to be glib, but taxes are a killer (at least in the U.S.).

Once you see all those figures in black and white you will know if your idea is doable. Will your idea be profitable after all those expenses?
