You need much more than that by the time you get it all together! Rent/buy property, utilities, equipment, inventory, referbishing the place, salaries, advertising etc....
And you need to be able to at least substain all the expenses for at least 6 months to a year before starting to recoup any money at all!
For sure if you just have $25,000 then you are out of business in six months and you might have as well just sent me a check... at least I'd be thankful. LOL
$200,000 is a very conservitive estimate to what it would cost to really have a shot at it, minimum.
