I'm located around an hour a half from you, but I have plenty of experience with both woodworking and carpentry. My family has a cottage up north in the Muskoka area, where I have built decks, docks, and cabins on our property. I've built something similar for my grandfather there to make it more wheelchair accessible, and when I was younger I had built ramps for my friend's and I to ride our bikes off of. I have all my own tools, so that wont be any issue either.
I can send over a CAD model / construction diagram of a ramp design if you'd like before I come out. I'm just looking to make any extra money I can to help pay for my university, so I'd be more than happy to help out with other things once your happy with the ramp construction since I have lots of experience with building.
