I have been a bitcoin user since last 3 years and I mostly use it like gold, an investment, and not like money. I have seen almost no acceptance to bitcoins and if there were some merchants, they were mostly websites, which have shut down.
So, I think you would need to develop or create your own UX. You can have a look at some bitcoin merchants outside India. I would strongly suggest to involve a bitcoin payment gateway so that you can track the payments. I have been using Unocoin as a wallet and they have a pg for merchants. Take a look.
