Not a scam... but a ripoff, absolutely. Go to Elance yourself instead of paying Mr. Lason outrageous fees to do that for you.
Ingenux will take weeks or months to create a contract that you won't understand, won't contain the stuff you actually need on your site, and then will hold you to that like it's the Bible.
If you're an Elancer, don't bother working with them. Looks like you'll be lucky if you get paid. Apparently, Ingenux can't handle their financial matters any better than their business. See below.
