ATV Options for a Paraplegic

So many of you know I'm a para and I'm building a home on 5 acres of property. I bought the land with my parents for them to also build their home and next door is my sister and her husband. Up to this point I've been using my brother in law's ATV to get around the property but that requires 1-2 people to help lift me onto it so I can ride. I "can" get myself on it but it's a huge pain in the ass. Technically I'm paralyzed chest-down so I don't really have any core/ab muscles but my upper body is very strong. I lift myself in/out of my Ram pickup truck all the time but my shoulders are pretty shot from old MX injuries and pushing this chair all day for 20+ years.

I want to buy a new ATV once my current house sells but I have no idea what really to look for. Ideally I would like to get something that I can easily get in & out of (or off/on) so I can make quick trips like 50 yards away just to get from point A to point B. I've seen some vehicles online but they are heavily modified for a wheelchair to get into but I don't know anyone around that could make those sort of modifications. My dad is a great mechanic and fabricator but he's very busy with building the homes plus making the changes to any off road vehicle is a very tricky thing. I just wanted to see if anyone here had any existing knowledge of something that might suite me or opinions on how to make it work.

I would also like to get a small tractor to build & maintain an R/C car track that I want to build once the homes are done but again, getting myself on/off the equipment is a challenge and I don't want to always rely on having someone help me. I'm really good at operating a bobcat but again...because of the enclosed caged seating I have to have someone help me get in it. My chair is like 3 feet away from the seat which is way too far for me to transfer into alone.

If you guys have any ideas, opinions, or suggestions on an ATV, Tractor, or off road vehicle for a para I'd appreciate the input. Or any modifications you've seen that I could consider. The best one I've seen so far is a guy who had almost like an elevated platform with a winch that he rolled up on, it lifted him up and he transferred over to the tractor but I was hoping for a solution that would be a little more.....simple.

Thanks guys.
