Dispatchguy,
Dispatch in DXB is performed by DNATA, the ground handling company, which is part of the Emirates group. They have just recently held interviews in the Uk for Redcaps, but I don't know if they received their full quota. Best thing to do is visit their website, and then fill out an application form online.

I am not familiar with how load control works within Dnata, but seek out the Blueboy on here, and they will be able to expand somewhat more.
