Sounds like you are getting some things done yourself though, that's good; I find that the most reliable way when I want something done. Do you have friends who could help you with some of the "construction" (i.e., making a matching other half of a ramp)? I think all the work you are having to do yourself is helping you with the energy; if things were "easier" I don't think you would have more energy, it would just sap easier; like any other muscle, you have to use whatever or it gets less.
