I contacted optimu with a request for a simple mod for a common EA.
It took him over a week to respond, but agreed to do the work.
He quoted a flat fee and agreed to start immediately.

I sent him the EA.

Weeks passed, he did not respond to emails and I never heard from him again.

I can quote similar stories from a number of coders who advertise their services here. I have to wonder why they bother.
