Looking for someone that can post advertisements for my business

I am looking for someone that can post some ads for my business in various areas all around the United states. I have a website that you can pull data from, and I have some ads that I am currently using. They may not be the best, but I get a couple calls from them here and there. I would also be interested in UK clients, as I have a few of them already, and I have been working with them for quite some time. We have been is business for a while, and we are looking to expand as much as we can. Any Free advertisement we can get is what we are going for here. So you would be posting my ads to free sites (some I mention and others you may know). Please let me know what questions you may have. I will be picking someone very quick, so be sure to send the bid fast, and explain what makes you good at doing this. Also give me how many posts you will do for the price you are asking. Thanks!
