Dori Smith has found an interesting way to keep track of her Mac consulting via iChat and a service called FlavorSofa. Dori notes, "The way it works is, say someone wants me to help with a project or answer a question. If they're a Mac user, I tell them my FlavorSofa IM account, and they contact me via iChat. They'll need to set up a FlavorSofa account in the first place (with a credit card), but after that, they can just ping me whenever they see that I'm available. FlavorSofa handles the billing (by the minute), and I'll periodically get a check."
Might be a good way to manage an at home Mac-consulting career for any of you industrious techies out there thinking about striking out on your own. Check it out.
