OK, I'll come a little more clean. We are starting with 25K (not counting lease) - and it isn't enough. Our business plan doesn't even have us breaking even for the first 6 months. It's a lot of money and a very scary venture. It's also a blast!
Good luck to you.
I am sure you know it but you might be a little under capitalized.
Once I did the math and the amount of beer I would have to make/sell (as a production brewery) was significant.
7barrel is not enough.
General consensus was if you have production brewery you need at least 20 barrel system.
To turn the profit you need to make 3,000 barrels/year.
And what is the most expensive is your tank space and cooperage.
Then you will think twice about converted kegs.
One more thing that gets overlooked is water usage, waste water, and amount of energy you need to make a beer.
I am on your team and holding my fingers crossed for you.
