I'm new to DotNetNuke and ecommerce both.  I've been doing web and asp.net development for years now, but I've only recently decided to take a more formal approach to providing side-project web design and hosting services.

I've become rather familiar with DNN, set up a several DNN Hosts, and created several parent-level portals between them.

I now have several DNN installations.  So far, only one of them has customer-owned parent portals, but I plan on having several.  One of my DNN installations is completely dedicated to a single portal/client.

What I'm confused about is how to go about offering my clients the ability to pay for my labor and hosting fees online.  I keep seeing WHMCS come up as I've researched this issue.  Does anyone have any opinions on it?  Is there a way to integrate it with DotNetNuke?  I checked SnowCovered.com and didn't see any modules for it.

Any advice or input would be helpful.  I feel a little overwhelmed trying to get my expertise to interested parties and get paid for it.

Thanks!
