Electric wheelbarrow #2

Hello.
I am looking for any help or advice I can get on my second wheelbarrow prototype.
I wasn't sure where to post this...I just posted a thread under "electric Technology/Motors & Drives" so I won't rewrite it here. Just ask that if anyone thinks they can help with motor and drive options, please read it.
I also posted some pics with my treads 6 0r 7 weeks ago of the first prototype I made.
My thoughts on where to get parts and motors:
I was looking at some of the new low end electric ATV's on the market thinking that maybe their motor and drivetrain could be used for my wheelbarrows. The cost of some of them seem to be as lower as what golf cart suppliers want for a replacement golf cart motor. I realize they don't compare and you get what you pay for.
Any other thoughts on a suitable (Non hub) motor that I could couple with a gear box would be appreciated.
Thanks, Terry.
