Hi Paprik, you need to be more specific in your requests. There's a lot of talented programmers out there, but you're not clear about what you need. Are you going to make the characters 3D? If so, that would require a TREMENDOUS amount of work, even if you used the models from Escape from Monkey Island (which wouldn't be a bad idea).
Using 2D models would be very much easier, as you could use pre-exiting software to create your adventure game (AGS -
www.adventuregamestudio.co.uk) for example).
You're clearly a very talented artist, I love the examples I've seen (and I imagine they look even better now, too), please don't get your project stuck while trying to find someone who's prepared to spend months creating a 3D graphic adventure engine.
Good luck!
