I think you have to incentivize it in the beginning. I'm not exactly familiar with your services/offering, but e.g.

• Get all your friends set up with wallets (e.g. Phoenix) and then help them pay you for your service there.
• You could do some competition on twitter, like for every 10th person that pays with bitcoin you will give them 100% discount for the next item in the same price range, or something like that (so this is literally just 10% discount that incentivizes next buy).
