Matthew, many grant-makers do not support the purchase of equipment since they are supporting a single project rather than a production entity which would be likely to make use of the equipment beyond that single project. However, many funders understand that independent filmmakers with their own equipment may include the rental cost of equipment in their budget (essentially renting from themselves) and that this generally ends up being more cost-effective than renting the equipment from a third party rental house.
Lynn, had you thought of asking the instructor of the digital video class you'll be taking at UC Irvine? He/She may be interested or have some leads on professionals in your area. You may also want to do a search on the People page here in D-Word and see who is in the area (or maybe extend the search to include LA) and contact a few folks who look like they have the skills you want. They may not be able to do it for free, but might be convinced to work for a fair price if they are taken by the topic of your film.
