Bitcoin does not work because people do not trust to buy things with bitcoin. I have a site running now for 5 months selling precious metals, made plenty of sales with credit card, bank transfer, no problems but not a single bitcoin purchase!
What is the point in bitcoin again?
You should promote it well and should offer some percentage of discount to those who will buy with Bitcoin.Usually people buy Bitcoin as investment and want to hold for some period and other use of bitcoin is transfer of money.In near future you will surely have clients which will prefer to buy with Bitcoin.
