Hi Joshua,
Check out this post http://developers.squarespace.com/business-marketing/post/925742.
Depending on the SQ package you need to purchase to create your client's website, I would pass on the SQ charge to them as a hosting charge or roll it into your monthly maintenance fee. On your SQ page you could create accounts for your clients where you can collect recurring CC payments from them.
e.g. http://websitesforjamaica.com/pricing/
Hope this helps.

I'm finally looking to venture out with freelance web design and I have a question for those of you who already do this AND use SS. How do you work out the hosting part since SS does charge a monthly fee? Is this something you add to your ToS agreement?
If you know where I'm going with this then any other information you can provide as well is very much appreciated.
Thank you in advance!
