Customisation of Magento Mobile Theme.

We have created a Magento responsive website. But we didn't like the default responsive theme of the website so we purchased a new Mobile Theme. The theme is working well but we need customisation like changing colours, creating a slideshow banner, and some more small work. We have also purchased a Multi vendor marketplace extension. This seller extension is not linked to the theme. We would like this seller extension also to be converted to mobile theme so that sellers could post the items with ease. Total job time should not be more than 5 hours I guess. We need this done on immediate basis. Only freelancers who are very very very experienced with Magento and Mobile Themes may apply.
