You know, I've found the first one I make of something is usually the most costly one. As I make amendments on each consecutive one, not only am I making improvments, but finding more cost efficient ways to do so. Once you get this thing rolling, another thought would be a lot of potential customers would be disabled folk needing your cabinet for medical grow. Keeping your cabinets reasonably price would be a great boon for them, but even then, on fixed incomes, may still be out of reach. You could devise a payment plan through credit/debit cards, doing the 3 installment payment thing. This is usually how I do my big purchases. Dont know how you'd set it up, but any business person who uses this practice could advise you on the 'how to's'. This could greatly increase your clientele (&therefore profits), & you would be a great humanitarian by helping mmj patients who are usually on fixed incomes. For talented people with a little vision, there's thousands of creative ways to be self-sufficient & help others in the process. The more you help, the more you succeed. Its a win win situation!
---- Ah..... just some thoughts for you to toss around!
