My consulting rate for working on site is $80/hour plus travel expenses (customer books and pays for my air flights and hotel, I cover my own food and incidental expenses).

I prefer to use my standard MASTER SERVICES AGREEMENT and NDA for my consulting services.

I am also happy to negotiate a custom contract with you. I understand that the simplified terms in my standard MASTER SERVICES AGREEMENT and NDA may not be compatible with your company's requirements. If you need to use your own standard contract, please include a copy when you first contact me.

For longer term projects I do accept remote work projects on a retainer basis with a minimum billing of 4 hours/week. My rates for long term remote projects are negotiable.

I have 30+ years programming experience and my customers have been pleased with both how efficiently I work and the quality of my work.
