I try to keep normal business hours, but understand deadlines don't always allow normal business hours. I'll work to meet every deadline.
Payment terms vary with every project and I'm happy to discuss budgets, payment types/terms, etc. I work with budgets of all sizes.
Email is usually the best way to reach me, but I'm happy to talk on the phone as well.
My website can be found here and has many examples of my work: http://www.matthewfhenry.com
