Create product images - combine vector img with picture

Our webshop [login to view URL] delivers wallsticker designs and we need more images showing them in the best possible way combining the different designs with different interior pictures. Combine our stock background interior pictures with our wallsticker designs (in pdf/ai format) to create finished images ready for the webshop. Would prefere to have a finished image both in high resolution and the native resolution used by existing images shown in our magento based webshop ([login to view URL]). We have ourselves used photoshop save for web with 70-80 % quality. The positioning of the vectors needs to look real, and they need to look nice. If you have any questions please ask. This task is for 30 images/product pictures. If the quality you deliver is good enough we hope to be able to use you in the future also as we plan on inserting several hundreds new items, keep this in mind.
