Interesting idea. It also would be worthwhile to explore the potential of a marketplace where you can buy and sell retainers or monthly maintenance contracts.

For example, let's say you built a website for a client and included a monthly maintenance contract to fix any security issues, yet you do not have the time to service that obligation. Then you could go to such a marketplace, sell that contract, and fulfill your contractual obligations.

I hadn't thought of that, but you're right, it's fairly common to have a retainer with certain contracts. It's related enough fit well into a site like that.
