Photoshop image editing

We need a photoshop export for ongoing work. We need photo editing, this includes cutting out the background of items, and using photoshop masks to change the color of the items (for apparel) to show different colors without the need for photographing different color items. We will transmit files by FTP. We will maintain one FTP folder for photos that need work, and you will upload completed photos to another folder. We hope to have a deposit account with the selected person and when we use the balance of the account, we deposit more funds. This way there is no need to bill for each photograph or set of photographs as done and you can work at your convenience. Please bid on this project on a per photo basis. It is not easy for us to provide exact volume at this time as our needs are ongoing, based on the amount of merchandise being purchased for the season.
