You can do this with ylastic - "scheduled tasks" - it's $25-50/mo (depending on the plan) for managing your whole AWS infrastructure and is basically an alternate WEB UI that autodiscovers your AWS footprint. Has some nice ways to manage autoscaling configurations as well, and also migrating AMIs between regions. I do not work for ylastic or anything but have used it for 2 different clients and used the "scheduled tasks" feature to do periodic backups of EBS volumes just as you've described you'd like to do.
