add custom fields to custom post in wordpress multisite

I need to add a selection of custom fields to a custom post type within a wordpress multi site. Also need the ability to use a global search from these custom fields and other fields. Should be a very quick job for the right person. Time is the most important factor. I will also supply login details for a "wpmu dev" account so you can download and install any plugins that might help. need this complete within a couple of hours.
