Pro version

Dear PickPlugins team,

I am team lead of the software development team and we are developing and producing laser machines in Europe ??
I was looking for some simple solution to demonstrate to our customer how they can bring their product to the web and integrate our laser to automate order process.
I tried out your Product design plugin and it works great however it seem to be able to attach the files to the order the “Pro version” required.
I was willing to setup very basic web page with help of your plugin to demonstrate to our customer how they can boost their business, however as mentioned seems being able to attached file of the customized product available only with PRO version.
Any advice would be appreciated
