Has anyone worked with Peak Models and Talent in Valencia? Are they a scam?

I recently met with Natasha, the owner of Peak Models and Talent, in Valencia. She seemed really nice, and showed interest in me. She gave me a contract, but I'm not sure if I should sign. I've never been signed to an agency before and would like to know if there's anyone who has worked with Peak Models and Talent or has been signed to them? I want to know if they are legit and not a scam.
