Dynamic Image PHP Simple Graphics Maker

We are looking for a simple PHP script that allows users to create simple graphics with text and some "brush/stamp" type effects. Basically we want a script that will create images shown in the example. It must have a way to save the files either to [login to view URL] or [login to view URL], the temporary files can be hosted on our website but cached to reduce storage space. Users must also be given the code for them to put the created graphic onto their website/myspace profile. The generator simply needs text, multiple lines of text, a way to freely rotate the text (an entire 360 degrees all the way around). For the effects/stamps we will need these items to be transparent somehow maybe placed on the bottom part of the graphic so it appears they are transparent or maybe the effects can be transparent PNGS so they can be placed wherever. We want the layers to be transparent but NOT the image when it's done, when it's done it will be a gif and there shouldn't be that many colors meaning we expect it to not be dithered or low quality. The text, and background colors must also be colorable meaning if they want a black background and pink text they can have it. Also we need the font anti-aliased meaning smooth around the edges. We're looking for a sort of extremely simplified version of Photoshop or MSPAINT that can create good graphics and save them with no stress to the user. Maybe an eraser tool, a way for us to add new fonts, new stamps/brushes etc. The content they are creating doesn't have to be animated but animation is a plus and Extra pricing is negotiable please let us know (optional). [login to view URL] is a quick idea I created to show the overall structure of the generator, You don't need to go by it exactly but we do not want something that isn't user friendly and we don't need something that is TOO much eye candy but we need it looking professional and easy to use, the people using it will be young teenagers to young adults. We'd also like to have a way for the quote graphics that were made to be viewable and browsable by the public. This is more advanced we understand but would be great for our viewers to get inspired or maybe they find one better than they could make so they would use it. All images created will need to have a watermark on the bottom corner that would be very very transparent, it would be in PNG format as well.
