I launched my MVP, Photosherpa. If you take too many photos and don't have time to go through them, you'd like it. You send all your photos to it, you get back only the good ones (so you can put them online right away).

Since I couldn't figure out Paypal integration yet, it is completely free :) Within December I'll try to integrate it with Paypal and Flickr/Facebook (so processed photos could get uploaded with one click).
