I have a fairly flexible work schedule. My preferred hours are from 7:30am - 3:00pm (EST), but I am also able to work in the evening and on some weekends if need be.
You can reach me by phone, text, or email. I like to schedule regular days/times to talk by phone, even if we've spoken earlier. This way, we can be sure to check in on a regular basis, see if anything has or needs to be changed, and make sure we are on the same page.
As for payment, I bill hourly to the quarter hour. My hourly rate for off-site work is $100 and $125 for onsite. If I am answering a quick email or taking a quick call (under 5 minutes or so), I probably won't bill for that. However, if those quick emails/calls become too frequent, I will have to start charging.
When starting a project, I like to make a project plan with milestones to make sure the deliverables are on track. The worst thing is to have spent hours and hours working the wrong way on the wrong thing! If you already have a plan in place, that's great!
Because we will not likely be working together in person, I feel that it is very important to be upfront about our styles. I am a straight-shooter. I say what I mean, and mean what I say, and I do that as kindly as possible. Boundaries are important for both sides. When is it ok and not ok to connect? How long are you willing to wait for a response? What is "important" and what isn't? These are questions that we need to suss out at the beginning.
