eCommerce enabling my website using nopCommerce

Hi,

I would appreciate some detailed advice regarding following please:

My company's website is at www.ienvisage.co.uk. I intend to keep the design intact but power it with nopCommerce for selling my eBooks and software(s). What can I do with minimum development effort?

After above is done, how can I sell digital products e.g. software, ebooks from this website such that a license key is generated only after payment has been received in my account?

A detailed step by step response will be highly appreciated.

Thanks very much
Jawwad

duplicate post - you dont need to post in every forum

I do apologise.  I thought that different background people will be watching different forums so I might benefit the most by posting it in different forums. I will be watchful in future.
