My two cents is two work on a project without even thinking of money. I myself don't even have the option to monetize with YouTube since I guess it doesn't support that in my region, don't get me wrong it would be cool to get paid but that should not be the priority.
When you say you tent to work a project half way only, I guess everyone has been in that position. There was an autistic kid who give a speech at Ted Talks who is a genius at match and he suggested that there is a point were you need to stop trying to learn and just produce what you know. I guess this constant searching to learn new things hold us back to apply what we already have learned.

Anyways I hope you find a reliable person to work with!
If you need help with 3D I can help with SketchUp and I do some animation there as well. Currently I am attempting to make a Super Meat Boy Fan Animation...the WIP thread is here;http://supermeatboy.com/forum/index.php/topic,2482.0.html
