Hi, person who's modded Mario Sunshine models into Garry's Mod before and who's done commissions for games like Garry's mod here. Allow me to kindly break down your logic. Firstly, a commission and request are two different things, commissions are paid for, usually for money or art trades or similar trades, requests offer nothing in return other than a possible "thanks" or some sort of praise. extracting assets from games like Mario Sunshine is no feat, and it requires more than tools, it requires knowledge of the file systems itself
the images below are two different file systems for The Legend of Zelda: Wind Waker and Super Mario Sunshine.
The image "lesson 1" reveals Wind Waker's content, many of Nintendo-based GameCubes have the four files above, which require specific tools/plugins to use and properly port, while the names are odd, stuff like "Aana" or "AC" contains a model of the character/object/enemy/etc and their associated props such as weapons. Super Mario Sunshine however, separates it's content by it's episodes, for example, Bianco0 has Petey Piranha's model in it, but not all of the other episodes except the one where you re-fight him, Casino 0 only has the objects for the secret mission in it, and 1 has King Boo, though both have the shared assets. Also in such cases, some names cannot be easily told of what is what, as they may even be based off their Japanese names or just outright letters, functionality or numbers,etc, one for example, the Darknut from LOZ:WW's file name is "TN", which is based off it's Japanese name: Tartnuc, it may be more simple given SMS is packed by episodes, but unless you can remember what episode is what and decipher the right formats (bmd,arc,rarc,szs) and names, it may be too complex for someone to just get off the bat.
Referring to your other thread(

as Xiahou ba said: "Every game that is moddable is different and has its own rules that you need to play by in order to successfully import, much less actually making it look good."
Not counting the fact your requests are not only complicated, but might be impossible depending on the game, there is a lot to take in, how the models look, the conversion from one game to the other, and (if it's even possible) to make them look decent without some sort of distortion/mass edit.
I sincerely hope this is something you are also not asking for free, because requests like this are ridiculously difficult and not worth any effort on a modder's part..
