I feel for you!
If you don't have the right son in laws, I can suggest an alternative: When I was laid up with an injury, I got some people off ads I placed on Craiglist under 'gig's (short term jobs, usually just a few hours).
I met great people, and they worked hard. I only had one 'dud' out of about 10 people over several months.
You just post what you want done and what you want to pay. Get some young folks to load up your tt!
I even did this once when I was interested in a van but couldn't get out to look at it. I had a guy go and take a ton of cell phone pics, scope out some details, and send all the info to my phone, for $25 :). Oh, and last summer I had a pair of college students scrub and reseal a floor for $10/hour...
