Have you checked the mods on this site, at MATY, MTS or Simbology as requested in the sticky for this section? If not, then that's what I would suggest you do first.
If you are looking for a mod, please take a look at the existing mods already made for the game. Mod the Sims, Simbology, MATY, this site and many others already have a lot of mods. There are so many different mods that do the same thing, so chances are what you want to have done has already been done. Check the sites I listed here first before posting here to request any mod, please.
