This is a standard response I use to save time and resources for all concerned.
I have over forty-five years practical experience in geneological and military history research. I can mention that I'm a veteran and that I served over thirty months of my four and a half years active duty in a combat zone but that's meaningless to anyone other than myself. Most veterans have been draftees who served two years or less and whose interest extended only so far as whatever they were required to do, whenever required to do it. Formal training has traditionally been brief and minimal - especially during wartime. I routinely encounter service members and retirees, with up to thirty years (and more) active service who, although highly proficient in their own respective areas of duty, are incredibly unaware of some of the most basic, common facts involving military history, customs and even rank and organization.
Over the years I've developed sources and contacts, few of which I share with others. Just one example. Not long ago, I could get an IDPF from TAPC in less than a month. I shared this with several members of an organization I belong to and, before long, it was all over creation. Now the average wait can be up to a year (and longer) and many, if not most, files probably wind up in the trash can - unread - or on a closet shelf waiting for someone to volunteer to "interpret" (free of charge, of course). TAPC is now imposing a "search fee" of up to $45 per file to reduce their "workload" and "recover their costs."
I have a small peronal library and do simple look-ups if I have the info on hand or if it doesn't involve more than a five-minute phone call or a special trip. Very often I have to pay a fee like everyone else. When this is the case, I pass it along with my other costs. I can reduce the waiting period in some cases but the main advantage is that I know where to go and what to ask for - which eliminates wasted time and resources. You benefit by accurate, usable information instead of stacks of paper you can't use - or even understand.
Many of the records you're seeking don't exist (and most never have). The information, however, is out there. It's simply a matter of locating the source(s). That's what I do and I do it well.
