Web to print or custom artwork creation

Hi all,

Was looking for a little bit of guidance on modules or adds.

We have recently had our company website re-built using EE. Off the back of this we have a number of projects we are trying to get off the ground. One of which is a marketing portal for customers to download artwork, assets and marketing campaigns. One function we would love to offer would be to allow customers to upload their logo and add in addresses or other customisable info to the artwork and then be able to download as a pdf.

Would anyone have any recommendations on where to start looking for a solution of this type. We have looked, but being fairly new to EE we are unsure as to what may be the best approach.

I assume the artwork would need customisable areas or fields designed into it, which is no problem but it is the software that will allow a user to customise and download that we are struggling to find a solution for.

Apologies if this has been posted and answered before but any suggestions or recommendations would be great.

Many Thanks
