Mod Request - NPC Addition, I would pay for this

I am not sure how easy is to mod BGEE at the moment but I have a mod request that I don't know how to do myself. I would be willing to pay someone for their time if they are able to set this up.

I have always wanted to have an animal companion NPC that levels up with the PC, so it starts at level 1 and is level 10 or whatever by end (and hopefully could move on to BG2EE and continue to scale). This companion in specific would be a hell hound. I don't care if the computer "thinks" it is a human or whatever, as long as it's looks and acts like a hell hound. No dialogue is necessary although some cool sound sets like snarling or howling or something would be extra cool but not mandatory.

I have lots of ideas as how to start it off at level 1 and then have it and its powers (breath weapon, etc) scale up but I will save those details for whomever wants to work on the project.

If you are interested and able to do a good job just let me know either here or email me at NPTITim@aol.com

Thanks for your time
