I'm sorry to hear about your troubles, Rickie. I well remember being without work, and having to take a job outside what I love, just to pay the bills. ( I ended up in a toy store for one Christmas season...the worst 8 weeks of my life. All those whining kids and nagging parents and rude customers...OMG I had forgotten about it till now!! It was awful.)
That being said, a couple of things came to mind when reading your post.
Some employers simply will not hire a designer with "letters". I worked for a couple of them. One was convinced that they would cost more per hour, and that would be too expensive, (false economics, we both know, but they do not.) The other had an ego too big to allow anyne else who may have greater knowledge, for fear that his superior position would be challenged.( again, we know that is not necessarily true, but....)
So from my perspective as an employer, in addition to so many great suggestions already posted here, most of which I suspect you would have already tried, I offer a couple more thoughts.
It might be worth a try having "calling cards" made up with your contact information, but without your various credentials. I must admit that I do not use my AIFD and CAFA letters on all of my correspondence, and even though my husband is an architect, he does not use his BA and BArch on all of his stuff either, because some people are just turned off by it, thinking that the letters automatically bring bragging rights.
I also would be really careful about revealing your ultimate goal of moving out of the area, to start your medical business. I would not ofer a job to anyone if I was aware they inteded to leave me once their house sold.
If you were in my area, I would hire you to help us get through the next three months...and I'd do it in a heartbeat, knowing that your skills would easily offset the extra hourly wage. Maybe some people just can't make a long term committment to you, and don't know if you would be willing to accept a short term solution? Have you tried offering your services at a reduced rate, with some sort of performance bonus? Or possibly offering to work for say 6 hours, and then have a discussion about your pay? That may settle down some employers who have fears about your skill and speed.
I'm intruigued by your situation. I don't get it. Is the economy really that bad in your area? Or does your gut tell you it could be something else?
