Ask HN: Bitcoin business unexpectedly taking off, help!

I launched a service to buy gift cards for bitcoin earlier this week (cardforcoin.com) and it's doing far better than I expected. Like, in a scary way.

I have a full-time job, and was hoping to carve out a small bit of passive income, not launch a full-blown startup.

I could really use some advice from anyone else who's run a bitcoin business, dealt with an unexpected success, or could get me in touch with a lawyer interested in the BTC world who might start pro-bono.

PPS - I want to leave the link for context, but if you'd actually like to use the service, please wait a bit / until the weekend.

EDIT - I'm not accepting cards until this gets on the road to straightened out, for obvious reasons. If anyone has any particular further insights please drop me an email.
