I have been designing for a couple years now, and while I have raised my rate in general there is one client who has been my bread and butter for quite some time. I manage all their sites and they keep bringing me new sites to build and maintenance to do on the existing ones. They are very happy with me. I have kept them at my original rate of $50 for over a year now. But the work is getting to be enough to where I need to consider bringing someone on, but I just can't do it at that kind of money. I'm nervous they will leave, but I really don't think they will. I plan on asking them for $65, even though my actual rate will go from $65 to $75. Does anyone have advice on doing this or best ways to present diplomatically? Thanks!
