Hown can i get a cheap engineer to fix my dish back to wall?

I am actually looking to find an engineer to fix my sky dish back to wall after it was removed from the scarefolding three days ago, sky want £65 to get an engineer fix it back but i don't have that much right now and am missing all the programmes on sky and am not sure if i can fix it myself cause i have been told it needs to be reset or something in a direction.
