If your a legit provider then you might be better served by exploring setting up a website. There are some sites that cater to providers and seem to be easy to set up though I am not sure what is required monetarily or otherwise.

Eros.com is a decent ad site. CL,Backpage,and Cityvibe have alot of scammers and BS and you might have trouble finding gents to agree to a meeting if you don't have reviews, which of course being new you don't have. Some non-GFE providers are listed on eros too, but those other sites are especially bad in my opinion, though this might vary depending on your region of the country.

I would consider a provider who has a website as legit, at least not a threat to be LE. Hopefully you can get together with a client who is a TER member and then your encounter can be reviewed.

You should also explore the reference system that many girls use to verify that clients are safe to see.

Good luck.
