I think a crowd funding in the cigar business can work, but more for a cigar. B/m? You would have to be in a large market, and I don't know if you are in one. You aren't going to get most of your cash from online with t-shirts and swag. If you offered package deals, or discounts, it might entice some, but that's cutting into your bottom line.
There was a cheese shop that crowd sourced near me, and it offered wine, classes, and discounts, but, once again, they didn't get a large pool (I think they only got like 5-10k) to help supplement.
Crowd sourcing only goes so far. Your business model is more important than 500 people giving you 20 bucks.
