Hi OAA,
I'm a geographic information systems specialist (in my full-time day job). I have the tools and experience you want for this project. If you pick me, I expect that I could finish this work over this upcoming week. Also, if you'd like, I can point you toward a free tool I've encountered in my field that would allow you to easily do later, similar jobs on your own. I'd love it if you'd hire me to do this initial batch, and if you do hire me, I'd be happy to enable you to handle any small batches that come up later in an efficient manner. If you wish to hire me, please let me know exactly how many photos we are talking about, and I can give you a better estimate of how long it will take me to complete the project.
Thanks,
Ryan
