UPS Or/And Fedex Module integration into existing site

Hi I need someone/ multiple individuals who are able to integrate a shipping module from 1. Fedex 2. UPS 3. Canada Post Into a website. Basically we build multiple e commerce sites and more and more clients are asking for integration of these shipping modules. We do not see the worth at the moment in doing this ourselves and would rather outsource it. As a result we are looking for individuals who can do this. Already I have 3 projects (1 confirmed , 2 potential) that require it. If there is one individual who can do all three , thats better, but if you are an expert at one let us know. We need qualified individuals, people who really know how to do it and have done it before. I would like to have a long term relationship as the person(s) we select need to understand our CMS and method of programming. We dont want to always work with new people. So this is beneficial for you and also for us. We can offer more services. Your work though reflects on us, so thats why I am saying we need qualified individuals. Cost is also important, so keep this in mind. Ask me any questions through the message board. We use PHP and a MySql database the CMS is something we built (not an opensource software) Thanks
