Please email me to set up a time to talk about your business needs.  Our initial conversation is free, while we discuss your requirements.  If you would then like to proceed, I bill hourly @ $250/hour, and invoice monthly for work done in the prior month.  I do not have minimums or monthly retainers.  I'm equally happy to do all the work myself, or to guide and mentor your team, if you'd like to keep costs down and become more self-reliant.
I strongly recommend you use the contact form here to set up a time for a call, as I can be very difficult to reach by phone--if I'm in the middle of  work for a client, I don't believe in answering other clients' calls on their nickel!
