Large Stitch project 1500 + images Hugin, Autopano or Ptgui

I need someone who is confident using Hugin, Autopano or Ptgui. You will need at least a year proficiency in this type of stitch project. Using control points is critical to the success of this project. Should take an expert in these programs a few hours to complete. I have 1500 images that need to be laid out over a 5 x 5 KM on a level map. Images are all Black and White and the exact same size. All images are taken in sequence and numbered according. PHOTOSHOP, and MICROSOFT ICE WILL NOT WORK!!! You will need control points It it very important that images stay native as possible. No gradient blending, and original size is very important. I think a powerful computer is important and a VERY powerful program is needed to do this task. I have tried the smaller free programs with little success. Thank you bidders!
