Ruby help needed for misc. issues

To the Ruby community:

We are a funded startup that wants to add the following features to
our existing Rails project:

- A permalink plugin to make sure our post URLs are SEO optimized,
- Resolving any IE 8 compatibility issues,
- Adding subdomain links to our navbar,
- Uploading KML files to our map as a new layer,
- Add a Site Map.

Our entire code base is on Github and it can be bootstrapped with a
rake task. If you're interested in helping us and our user community,
we look forward to hearing from you. Thanks!

Thanks for the response. What are your rates, and how much time would
it take to do this? Also, is there any warranty on the work for bugs
fixes, etc., if needed?
