In the near future you will be able to use paypal via the paypal API to make a donation to lostpetnet.com while listing a lost or found pet. This way you can specify an amount of money and tie it to your listing. We don't have any plans of implementing automated rewards as you can put that manually in your listing, but we will flag your listing with a sponsored star which will identify it in the search, and bring it to the top of the list.
