Pink Razr V3 Question

My finacee purchased a used pink v3 razr after she dropped her other pink razr in water. I wish to have the faceplate, and housing changed from one to the other.

Two questions -
Is it easy to swap the faceplate/housing and do it myself?? if so where would I buy torx screwdrivers as I have no idea where to buy them??

Would I be better off going to someone else and having them do it ?? And where would it be possible to do something like this for cheap??

take it to pacific mall
