I do completely understand. I never do anything the easy way. I have picked an era I like and would like to stay in it. If I can figure theses out my plan would be to venture in to the other radios I have access to (p110,mt500). I like the ht1250 series but I do not believe they are programmable on the software in my possession already.
All this is one of The reasons I came here. For guidance. Once I have a set of 6 with the bank charger I don’t anticipate expanding.
Legacy radios, especially ones as old as P110s, require three decode old PCs, hardware, software and skills. MT500s are crystal controlled and there are maybe a small number of living people who have the knowledge to tune/align them let alone finding someone to re-crystal the channel elements if you can even get crystals for these relics anymore.

The radios you mentioned are decades out of their support cycle, so parts may be difficult (or very expensive) to find. Also, I wouldn't expect many qualified service shops would have the manuals or the desire to service vintage equipment. Shop around a little and see what the going rate for bench time is and compare that to the cost of each radio.
Someone competent would be more than those radios are worth.
Whoeee! That means my entire inbred family can use them! That would be nearly the entire trailer park here.Federal Register :: Request Access

When repeaters are moved, they often require tuning on the duplexers. Repeaters are NOT for novice or inexperienced people regardless of the source. I guess if you're willing to take the time to learn have at the very least a spectrum analyzer with a tracking generator or other calibrated source to fall back on, then and only then would be the repeater be a good idea. (in my humble opinion). I hauled a set of cans (duplexers) from where we worked on the repeater system, back to the tower site and it a 15 mile ride simply carrying them around and then I guess the car ride, we had to touch them back up.
Ok and we've honestly tried to do that. You are bound and determined to use antiquated radios, that very very few people living today can honestly competently work on. While I'm personally ok with that, I work on 99.9 percent of all my own equipment and have for years and years. Frankly it's this new modern scanner programming that throws me for a loop upon occasion, and I've received help here often and frankly getting ready to post up another question. As was mentioned earlier, I'm not even sure what those radios are certified for, you'd have to check that yourself, as the operator or license holder it's YOUR responsibility to make sure anyone operating under your callsign has properly aligned and certified equipment.
This is without a doubt, the best answer here, due to the lack of experience, understanding and apparently some confusion on your part (I guess anyway) about exactly what GMRS is or what it isn't. You're not going to have a repeater for the DTR's but truthfully for what you've described they'd work ok I think.
Part 90 Itinerant frequencies don't require coordination. But, of course, they're meant for temporary itinerant use.
As long as every individual has their own GMRS license since the FCC has not issued GMRS licenses to businesses in quite some time.
Right. Except I would tweak that statement a little: as long as every individual is covered by a GMRS license.
Big farms still can use it "all the time" as long as everyone is covered by a license. Although I doubt these days this is a desirable solution. Part 90 coordination is about $500 one-time. And licenses are $200 for ten years. It doesn't really make any sense to use GMRS for that and other reasons.
The problem is that the owner of the farm gets a license in his name and then just hands out rails to all of his employees that don't have licenses. The second issue is that they tie up the repeaters so that no one else can use them.
