Part to Full Time Independant Programmer for ASP/SQL/ASP.NET work

I need to add another programmer to my 3-person team. I have a software development firm which services a variety of clients and exciting projects. The work is about 60% ASP/SQL SERVER, 20% ASP.NET/SQL SERVER, and the remaining 10% is VB.NET and client-side MS Access (using MS Access forms/reports/VBA to create desktop applications). I'm flexible on hours but would need someone who can put in at least 12 hours per week of work, and I can't guarantee more than 20-30 hours per week. I do NOT want moonlighters. If you have a full-time job, please do not bid. I do NOT want project managers/recruitment companies who have "teams of programmers". I want only the actual person who will be doing development to bid. I would also prefer to have someone in the Western Hemisphere (US, Canada, Mexico, Central or South America). Basically I'm looking for an independant developer who would like some ongoing steady work.
