6000 car images renaming and uploading to wordpress blog

I have 6000 car images and wallpapers that need to named properly and then uploaded to my web site as galleries. Each gallery can have maximum 100 images and it will have to be placed within a post. In addition each post needs to have a proper title describing the gallery plus 3 lines of text description. For each post you will also have to assign 4-5 tags. All galleries need to be focused around a certain keyword theme or brand. This project needs to be completed within 2 months. Half of the money will be paid as an initial milestone and the other half after 30 days. I will not accept offers that ask for all the amount to ne paid from the beginning.
