Hello,
my name is Josef, i'm freelance developer from Czech Republic, and i would like to offer you my services for this interesting project.
I have checked the example website, and read your specification very carefully, and i'm confident i can create one-page web tool implementing the required features (as per example + clear exif data, set title, subject, rating, tags, comments; converting images to jpeg isn't a problem and same as the additional geolocation / reverse geolocation using google maps api) to your full satisfaction.
If you considering me for this project, please don't hesitate to contact me by chat any time. I'm looking forward to hearing from you soon.
Kind regards,
Josef
