Anyone use fiverr for logo design?

[~kev~]

I joined fiverr and am looking for someone to make a logo for me.

However:

The people I message do not reply after I send them the picture I want a logo made from.

Sellers do not want to provide concept art before the order is placed.

Overall, I am starting to doubt how honest the sellers are.

The logo want is a sketch from a picture I took. From what was told, a to of logo designers on fiverr use templates and are unable to do original concepts.

Has anyone here ever used fiverr for a logo design?

Please do not post your sales pitch here, I am no interested.

All I want is some tips on doing business through fiverr and not getting ripped off.
