The website it's about printed vertical & roller blinds.
I need a shopping cart module – users will select an image from the existing online gallery or upload their own picture. The upload feature will check the image size/resolution and will notify the user if the image is suitable for large format print or not. It will be nice to have a “crop” feature – users will choose the print area, it will be a fix rectangle/no resizing.

The selections:
Image for print
Mount: inside/outside
Control options
Width
Drop

The script will calculate the final sale price.
The shopping cart should be Paypal integrated.

If necessary I can provide few URLs – similar modules.

Please PM/email your offer.

Thanks.
