Right, some multiple of profit, not sales. While I hear sales multiples thrown around in terms of valuing a business, I think those are just after-the-fact averages. I don't see how sales alone can tell you anything about value. Sales in a declining market, and/or sales with little/no profit are not worth much, may even be a liability.
Yep, multiple years records, tax forms, etc are needed to paint a picture and a trend. Lots of negatives have been pointed out, I don't see how this can make sense at all, and I'd be even more worried that some unexpected cost (repair, lawsuit, etc), could wipe out all the sales, let alone profit.
This seems far riskier, and far more work, than putting the money in an index fund. Would you put $325K into a single stock? I wouldn't, and I wouldn't recommend it, unless you want tp 'play' a little, and $325K represents less than 5% of your liquidity.
