CUSTOM WORDPRESS MODULE NEEDS UPDATES & IMPOVEMENT PHP CODER WANTED

We have a wordpress module which outputs HTML for use to copy and paste into ebay as a listing. There is no direct ebay API. The module is able to create multiple style pages via a template system. 1) We need a coder to update the standard html editor (tinymce) etc. 2) when adding weblinks to descriptions the code always adds ./ or similar infront the URL. 3) The most important problem is the image editing engine on the module, edits images out of ratio. This makes them looks stretched and the aspect ratio is not maintained, this needs significant improvements. So any size images can be used and the script with create images within aspect ratio. A few images of the script are uploaded. You will need to work on the updates locally or on your own webserver, full code will be provided.
