Ask HN: How best to pay offshore resources?

Hi, I have a consulting S-corp that I've been running for about 6 years with me as the sole employee. I use Paychex for payroll, and all my contracts are corp-to-corp. Now, I'm trying to bootstrap a startup, and I have a lingering consulting project that is about 70% done, and I want to hire someone to help me finish it, so I can devote all my time to the startup. I ended up finding a great resource, and it just so happens that he is Romanian. I didn't go looking for an offshore resource, it just happened that way. Anyway, I'm unsure how best to pay him, and I was wondering if anyone on HN might be able to provide some guidance or resources?
