recommended recruiters/temp agencies?

I was recommended to try temp agencies and recruiters in hopes of finding a job. I have around 6 years of admin/office assistant and customer service experience in various fields(construction, engineering, and legal).

Does anyone know of temp agencies here where they’ve found (relatively quick) success?

Not looking for job boards or websites, they’ve been total dead ends.

I’m not picky at all. Just don’t want to keep sending my resume into the abyss to die.

tyia!
