Youre going to be offering a lot of compensation lol. Here is the order in which I would do things before creating a thread:
1. Search the forum. There is probably not a single community out there with as much free media as this one. Search and you are likely to find most, if not all of what you might need.
2. Look on FPS-Files or the new backed up version of FPS-Free. These sites have an enormous library of free weapons and other media that can be yours at the click of a button.
3. Look on the GCS Store for rifles and pistols. There are bound to be a few.
4. Look on GameBanana. This site offers numerous models and other stuff from games that you can use in your own, NON-COMMERCIAL game.
5. And finally create a thread. This I would reserve as the LAST option if I couldnt find any media, because hiring a paid artist IS goign to be more expensive than any of the oiptions stated above

Even buying a model from turbosquid and rigging it would probably cost less...
Trying to save you a bit of money, because if youre anythign liek the rest off us, you like having a heavy wallet

now if you still want to hire someone, I am more than available
Cheers,
Anayar
