Hi Sarah
Are you aware that you've got "its" instead of "it's" on your home page? (it's that simple)
Also one of the headings in your T&C isn't bolded....
Sorry, not meaning to be critical but typos on a typing site may put people off
Personally, I wouldn't be careful about where you post your website, the more places it's on the more chance of showing up in searches and clients finding you. I don't use craigslist, but there are heaps of other free directories you can list yourself on - Hotfrog is a good one as it shows up in Google searches if you use the right keywords and make sure you enter lots of products and services to bump up your listing.
As for wierdos, unfortunately it does happen, all you can do is try and ignore it and move on.
