Photo cropping site

Hello folks.So i was thinking of making a photo cropping website ( I know there are a plenty already) where users can upload their photos,crop them,then save them to pc or share to social networks.I have the perfect domain name for it.(very very unique). In the first week i'll work on the websites design and system.In the next few weeks i'll run the SEO campaign for the site.

My questions are:

• From where can I get such a software for my site and total cost?
• Would I be able to monetize this site?

Need your opinion and suggestions.Cheers!
