Coldfusion Developer - add theme editing & pay gateways to ecommerce app

We are looking for a coldfusion developer to work with us helping to add features to our existing ecommerce system. Initially there are 3 main areas to work on. - Theme Customisation for clients Currently customers who buy into the website system can choose a theme upload a logo and in some themes change the background colour. This is currently a very basic form, we would like customers to be able to upload, crop and adjust the position of a logo on screen possibly using a inline live preview. Change the background colour and images of body and main divs. Change h1,h2,p text colours and apply google fonts. Upload header and footer graphics, crop/scale image inside browser controls. We have build current theme using our own simple theming system which we will be on hand to help add these new controls - Payment Gateways Add Paypal Pro and Payment Sense payment gateways to our existing checkout system (we have already added Paypal Standard and SagePay Direct&Form) so the most the page and database structure is already in place. - File Upload We are currently have issue with our uploadify file uploader for customers to upload print files to use we would like this system to be bug checked, possibly converting it to an alternative, reliable script such as swfupload
