Testing the waters

Hello Everyone, I'm currently in search of someone who knows how to make Ped's for GTA IV. I am attempting to get a ped made to replicate a star on the show Chicago PD. i'm not too sure how difficult this request is going to be for someone to do as i don't have too much knowledge when it comes to modeling. i'd like to try and get three versions made though obviously utilizing one ped and in game just changing the clothes around. I'm going to attach a picture in which will give a general idea of what i'd like to get made aside from the details that i am about to mention. first i would like to get a badge placed on the right hip which will be semi visible while wearing the jacket along with a Glock style hangun holstered on the right hip (Wont be visible while wearing the jacket), i would like to get a version made where the ped has a T-shirt on and both the badge and gun will be visible (T-shirt sort of lays behind the gun as if it were tucked) and the final request would be a Kevlar vest  over top the T-shirt in which both weapon and badge would be visible. if at all possible i'd like for the vest to not just be a texture but actually look realistic and show off the ped if that makes sense. i'd personally try to do this myself however as i stated earlier in the post i have no knowledge on creating this sort of thing which is why i am here requesting some assistance from the great modelers that reside on this site. If this is something that you'd be able to do please feel free to comment or send me a message. 

Thank you for your time!
