I need to mirror 84 sites and I need someone who know PHP for a long term collaboration

I need someone who can help me with long term colaboratation . I need to help me mirror 84 sites and I also have a PHP script created by my IT specialists . I need to be changed in order to mirror the sites I want and to change few elements in the mirrored sites . This is a long term colaboration as if your work is great we can collaborate in other projects. This is a basic task but I would like to know if you can also provide also a free sample with changes and the result for at least 1 site to know if you can actualy done this . As I said I'm locking for long term collaboration . Only bid if you are able to done this and know PHP. My budget for this task is 7$/1 site . I have the script but need to be changed for every site. Thank
