@Mastoras007,
You seem to be passionate about pursuing this and I cheer you on to follow your dreams!
My suggestion would be to create a business plan and then schedule time with a consultant to discuss things in detail.
Make sure this contains equipment, rental space, licensing information, insurance, build out costs, raw material costs, refrigeration, labor, etc.
From there you can truly assess the cost of doing business.
Also, whatever time you had planned to commit to this should be at least doubled. I'm not kidding.
Here's a good question. What is the draw? Is your beer better or cheaper or different than what's locally available?
Just brewing beer is the easy part.
Good luck,
Brian
