My last site (still not 100% complete), I probably came out to $1.60 and hour. Bad job, scope creep doesn't even begin to define the problems.
As for the 10 years... 4 of those 10 years has been part time, freebie, portfolio builders. 6 of those years have been professionally employed with more freebie portfolio builders on the side. The professional side has given me experience in every technical facet of development, deployment, management, disaster recovery and maybe some other things that I didn't find tangible, except for pricing obviously. So don't look at the 10 years as a complete independent developer. Good experience, but under someone elses management umbrella. I'm no design phenom, but I have solid practical skills.
I'm trying to move forward with the business side in mind. It's been said many places, many times, that web dev skills are only small part of this gig. Keeping business in mind and shooting for $10 an hour seems pretty generous. Nobody is going to pay $50-$100 an hour for html, css, php, mysql and a decent sense of site design for user experience. At least not anywhere around my neighborhood.
So I should flop the customer with a $500+ estimate for a 5 page brochure style site with an upgrade or two? When they start laughing, do I laugh with them?
