Cost of open new food business

Hi

I'm currently based in Iran and I'm moving to Tbilisi with my wife and my son in next Jun. My idea is to start a small business there.

My sincere apologies for the barrage of questions, as I'm really factoring in many considerations for my budget.

I wanted to know the following:

How much money is required per month for a family of three?

approx idea for 2 bed and school fees ?

My son is going to grade 10 and he can speak English as native .

How easy is it to start a food business? Do I need a special visa?

Is it good idea to open fast food restaurant ? can i cover the expenses ?

Thanks a lot!
