Website add on

I am after a add on for my website. I need to be able to post images privately to my website and have client be able to make comments, mark ups and general proofing of the image and then me be able to make changes to the images and insert a 2nd or even 3rd revision for the client to make mark up on. My current website is [login to view URL] and I want it to look similar simple feel and do all the similar things that [login to view URL] does. Accept I need the ability for each time the revision is updated or revised to have all parties emailed each time. Another site that does this well is [login to view URL] or [login to view URL] The thing I like about picme is that it is clean and very user friendly. I need to be able to have login capability for myself and clients. My site is done in Wordpress. I need this completed asap and will only take quoted prices. I will have a Mock up for the web developer to work off for inspiration. Please make sure you can start this work immediately and quote your total price in your application Thanks and good luck
