A year ago I have modified popular Mimbo Theme to get two Boombo Themes (which are in 90% of code same themes) for our WPMU installation. Mimbo was not using child theme system like it does now. At that time site was (and still is) running on 2.6.3. Now I want to upgrade to 2.7.1 but some problems appeared with our themes so I guess I'll have to upgrade them. I would do it myself but I know it will take me a week to find out what needs to be fixed and I don't have extra time to do that. I don't want to build new Boombos using newest Mimbo as the base template. I just want to find/fix bugs and make themes work with newest WPMU. It will also be great to get rid of some extra code which has left behind. You can see our themes in action. So if anyone would be interested in helping (fix themes so I don't have to) please let me know. Also, please tell me how much would that cost.
You can send me email to pinkforrest[at]gmail[dot]com or reply here at WPMU forum.
Thanks!
