Without to much customisation (devil in detail for requirements/features) but you could get that up and running to a degree with your experience but your also limited using Muse, its not a coding app.
From that though the PDF element would need custom form on the ecommerce confirmation page which should be something you can do.
You just need to go through the docs:
Or outsource the work to a developer
Thank you for your swift response. To clarify I was hoping to build the site in Muse and then ‘bolt on’ a ecommerce store created with BC. I am fairly happy with working with muse to achieve the ‘design agency’ feel I need form the main site but am totally new to any ecommerce stuff in BC.
Could you point me in the right direction to start this sort of project.
Not really as I do not use Muse.
