AWS EC2 Instance Manager - repost

I need a console application in C# that allows me to manage AWS EC2 (Amazon Web Services Elastic Cloud) spot instances for a particular region. The App will have a config file for....... 1) Region Name 2) Availability zones (for the given region) 3) % higher than spot to keep incrementing (ON DEMAND PRICE is the MAX) (same rate for all zones is fine) 4) The number of instances i want to keep spinning up and their "RECYCLE TIME" 5) I want to check a DB for messages that say to delete/recycle a particular instance because it's having issues. (I have an app that does health checks already and can send any kind of delete request message to a DB table). 6) I'll provide the name of the ami and instance type to use. 7) I would like this app to be able to recover from failures. So if it gets killed/restarted it gets its last known state from the database and resumes its operations as normal. 8) A Table with all the currently active instances will need to be maintained by the application. ***Recycle time is the amount of time before terminating an instance and spinning up a new one. If you have any questions please feel free to ask. In your reply please include answers to the following questions: 1) What is your experience with AWS and EC2 API? 2) What is your availability for future work/support? 3) Is there anything else i should know about you?
