Hey,
1st, USA born and raised, no language problems. If the problem you are talking about is CL's recent clamp down, I can tell you what is going on, and how to work around it. I am a team of one, and have personally posted over 250,000 live ads in the past year. I do not use auto posters. I have 24 ips, over 100 accounts, I know how to set up proxies, and I know what is going on with CL now.
Of course I would have to see your ad first, but I will post 20 for free as a demo. After that I would charge 75 cents/ad, guaranteed live for 24 hours. After CL loosens their reigns I will drop the rate. I do ask to be paid weekly, in advance.
However it goes, good luck.
