The first sentence tells me nothing -- from reading it, I don't know if you're a mechanic, a teacher, an engineer!  Avoid all generic language and be specific about your skills and strengths.  You can list the temp agency you've worked with -- along with the full dates of employment and then specify the nature of the assignments.  As long as you make it clear that it was a temp assignment, you don't risk looking bad because of the moves.  Employers understand the nature of temp work.
