Is there anything available open source that even comes close to the lambda job you're mentioning? It sounds like it does the job of finding the cheapest possible price at runtime, and would probably have to be pretty custom. I think an open source baseline would demonstrate you could do the customization, but with that kind of savings you have the opportunity to do this full time as a consultant, open source or not!
