I'm glad you found something that worked well for you - I don't want to be a spoil sport but my only caution with these forms that are hosted on someone else's site [their server processes the info and sends it to you] is that they are not always secure and they may be harvesting the email info your clients and potential clients enter. I just think it's important to be aware.
I'm also a little concerned by the implied affiliation with some major players on the net as well as some very evident spelling and grammar errors on their home page and FAQ page [those are the only two pages I scanned]
