Modifications needed to Joomla 1.5 Module

We have a Joomla 1.5 Module that is a combination thumbnail carousel/slideshow with lightbox overlay when user clicks on an image and we need some modifications made to this. This will require knowledge of jQuery, PHP, MooTools and JavaScript. The basic tasks are: 1. Ensure lightbox functions correctly and shows images from 1 x directory as an 'album' not individually. 2. Fix load order of images. 3. Move thumbnail directory. 4. Fix spacing issues in different browsers. 5. Fix lightbox 'caption' height issue (remove caption height entirely to show fullscreen images) 6. Fix loading of images on initial page load. 7. Alter image file name generation. 8. Add option to link to url instead of image in thumbnail view. 9. Add transparent .png overlay on top of all thumbnail and lightbox images to prevent visitors grabbing images. We are only interested in those coders that already have experience in this type of work and a full project brief will be made available to confirm costs with the chosen coder. Thank you.
