When I went back to work after 17 years at home I went to a temp agency. It was a good way for me to get used to working full-time again. I worked several temp only positions before I started working temp-to-perm positions. Some I did not like and some did not like me. It was a good way to prove myself as an employee before being hired. I have been with my current compsny for over 3 years as a permanant employee. The only way to get hired where I work is through a temp agency and they are not the only company that hires this way. If you haven't tried it you may want to give it a try for a while. Some also offer training to update your skills.
Good-Luck!
