I just build websites but that other guy can help with the Programming. So we all can work together
I like the enthusiasm, and I am all for teamwork. I have done web design, and I have done some actual development (Java, C, etc.) I am a very basic amateur in the dev and design side of things, but I know enough to see that this is something I would stay well away from without a heap of money, existing infrastructure already serving a similar purpose, mastery of the appropriate skillset, or preferably some combination of all three.
There are also major legal hurdles, assuming that you are in the US or dealing with US customers or both. For
example.
If the two of you do decide to work together, at least plan out very seriously what the jobs of each are going to be. "Partnerships" often end in tears, even when both sides are capable and competent but in different areas - never mind if one or more parties are incapable, incompetent, or working under wildly different illusions about the work and potential profit involved. As the ongoing saga with DHS and MtGox shows, just the regulatory hurdles can be kind of a big deal when you`re working with money - and "value transfer systems" are still money in some sense. The legal treatment of Bitcoin is still evolving.
I wish you guys luck if you do decide to do this - but I hope you establish a genuine, well-considered plan before you get started - and that should include what to do if you decide to dissolve the partnership.
