Well, sign up here - it's free - then we can all say
Then get yourself signed up for email notices at "cars & rollers" in the classifieds here, do the same at 914club.com , clubNARP.com & Pelican Parts classifieds, also sign-up under the Porsches under classifieds at TheSamba.com (or scan it every so often) & get online to Lycos for a email notice of anything 914 in the markets you're willing & able to drive to see/get a 914. eBay is out there, but I wouldn't buy anything I couldn't see, drive & have fully checked out on there.
For a grand, you're mostly going to find rollers & projects, not really much in the way of a safe & reliable driver, and it will probably be loaded with rust problems. Have a local Teener in your Roanoke VA area help you check out any cars, as there are some on here. Scottyb (screen name here) is near you too & knows a lot, does bodywork etc. for many of the 914s on here (you can search in members then PM him).
Good Luck!
