writing advertising for companies

I know this seems to be mostly a technical oriented program and I am new here but what I wanted to ask is this.. My expertise is writing advertisement copy for businesses. I wrote ad copy for ad agencies for a few years and if it is possible I would like to get back into doing that online. Is this the wrong place for that or would freelance.com be a good place to get into that? I really do appreciate any inout and greetings to you all and have a blessed day!
