I think what you have here is a good idea. Clearly the PaaS and IaaS markets as heating up and it would nice to have a one-stop-shop to spin up the servers you need. However, I don't know that your prices are framed properly. Your marketplace makes it seem as though I'm paying $12/mo for running MySQL (which is free to use is most circumstances). This might come across wrong. Instead, consider developing a "configuration" panel for the type of server the person wants and point them to a provider who can supply it. Then allow them to add "free" packages to those instances. In other words, make it clear that they are paying for server time, not for the packages you're deploying.
