Snack bar inside car dealership?

[brill]

The owner of a car dealership in my area asked me if I want to operate a little snack bar for free(no monthly rent).

The snack bar looks similar to this (w w w.archconcepts.com/New%20Cafe-Snack%20Bar.jpg) There is no built-in stove/oven for any cooking on site. That means I have to sell mostly cold foods/prepackaged. I plan to sell cold sandwiches (turkey, ham, tuna, italian combo, etc), pizza, chips, candy, hot dogs, drinks (sodas, coffee, water), milkshakes.

Equipments such as a small deli case (to keep sandwiches cool), pizza warmer, hot dogs warmer, refrigerators, cash register, would cost me an estimate of <$4,000.

My customers would be the 100 employees and customers from sales and service departments. There are restaurants near the area but requires driving. Employees normally go out to buy lunch and food during their break.

I plan to prepare the cold sandwiches (turkey, italian, ham, tuna) at home the night before. The only cooking I can only think of is the pizza being heated in a portable home size oven. I will probably buy already-made frozen pizza and just heat it up on site; similar to Digourno's pizza.

I have no background in business. I'm just a college student.

My questions are:

1) Is 100 employees + customers a good size of customers? I already have in mind that not all 100 employees + customers will buy food.

2) What kind of license would I need for this type of business? How hard/easy to obtain the license? How long does it take to be approve?

Assume 1/3 of the people continue to go out to lunch & 1/3 bring their lunch. You have approx 30 sales per day.

What do you expect your profit margin on a typical sale: sandwich, chips & drink will be after you cover your costs of material (food, cups, utensils, napkins, etc)? Will you be paying interest on the $4000? If so, subtract that out also. Subtract out your taxes also.

Whatever is left is your take home pay. Divide this by the number of hours you spend preparing the food & selling it & the result is your hourly pay.
