I would try to structure your business in stages. Have you thought of venture partnering with other businesses in your area to find shelf space instead of going all out for store in the beginning? This MIGHT (as I have no data on your industry) give you a leg up in selling some product in the beginning and possibly give you a track record with a supplier or two that you can further leverage. While it might not give you exactly what you want, you might be able to get better buying terms (net 90 or better) that could help you with immediate cash flow relief. Another option might be right in front of you... going virtual and venturing with galleries etc to get you in front of local prospects if that is the market you want to stick with. Hacking off the need for floor space and employees, and even trying to get away with preselling before purchasing will relieve most of that debt need. I have found from recent talks with VCs that the idea of investing in anything other than an established C-corp with an established record is a waste of time if there is a single brick involved anymore. Not that they are looking to jump back into another .com boom, but the risk is seen as completely non essential and thus an unneeded risk and expense. I am NOT saying to follow up on vultures... for obvious reasons, but these boys are usually looking 5 years ahead of any other investing org, and about 25 years ahead of anything 100% conventional.
I do think crowd sourcing might be an option IF you are able to raise a good percentage of it before you place your project in front of them. It also helps to have a "feely" twist in mind and pick the appropriate CF platform in the beginning KickStarter is the biggie, but they are not the only name in the game.
You might have to split your goals into smaller pieces to get it done, but bootstrapping can not only get you the money you need in the beginning, but ut you in a better financial position when you REALLY need the money, in the growth stage that comes right when most people start to have to deal with their startup debt. Undercapitalization is the main source of business failure (80%), but is usually 100% avoidable, especially today.
Good luck... Never give up. That's where the 95% that never start up fail and where the other 20% that do usually fail.
