Have you looked at Zoho Sprints?
https://www.zoho.com/sprints/
edit: Suggestion, compile that, the bug tracker and a Git repo service into one bundle. It'd definitely sell.
I enjoy the product a lot but when our IT people first sent us the documentation and accounts I thought I had clicked on the wrong link since the design of Site 24x7's dashboard and the Zoho site seem so different
