Build an online Logo Generator

Hi, I'm looking for a bit of help getting an online tool that can either be hosted on its own domain, or in a word-press site that can generate logos. There are essentially 2 formats for the logos I'm looking to create (constrained sizes). I would like the clients using the site to be able to: Add in text (select font, color, size, and placement) Add in basic symbols (select size, color, placement) Upload and size their own images (for use as background). Once the image is finalized I would like them to see the image as a jpg file in a final proof layout- then they download it (if they choose to) and FINALLY have it sent as an attachement (JPG) in an email sent to me. Would like this to function similiar to [login to view URL] or [login to view URL]
