plug-in with crop image for VM2

[timoleon]

hello and happy New Yar.
I am trying to build a web-site with joomla 2.5 and VM2. Trough this website I want to sell printing in different size and materials and I am looking for a plug-in that I can crop images in the desire dimensions and calculate the prise for the new dimension. the price also would be effected from the material that would be chosen from the customer.... any one that can help with this??  I would like to find a ready plug-in or to discus with some one that can create it from scratch
