Thriftymember is right, there are ton`s of lead generation websites out there that will allow more to come to you. elance.com, guru.com, odesk.com.
I`ve run the networking tour before for my past business. It can be extremely time consuming - and time is money...eventhough many entrepreneur`s don`t add it up that way.
There`s also a lot of fairly cost effective lead generation companies out there, as I see StartUpNation.com (who I believe works with ResourceNation.com - not sure on that) is promoting free quotes for web design on the right hand side of my screen right now.
SEO can work, but of course it`s so competitive for Web Development (since most SEO companies also do Web Development).
Or, of course you can do some searching to find your own gem. I know a PPC company that can generate exclusive web development leads for $22-30/lead, and they have a 5% closing rate guarantee (which is extremely unique for lead generation...and a nice assurance). Although I guess if you don`t close more than that, you also have another issue...your ability to close. They will only work with those people who buy a minimum of 100-200 leads though.
There`s also email marketers, telemarketers and affiliates out there who will also generate leads on a per lead basis or per sale basis - you just have to find them.
