Google news site issue (needs fixed)

Hi, I need someone who is familiar with Google news. Here is exactly what my issue is..I have a site that is accepted in google news (Google have confirmed this via e-mail) however they are having trouble indexing posts / discovering content - I have a news sitemap and a regular sitemap however within the last month or two my site disappeared from google news (Again they have confirmed my site is included AFTER the results disappeared). I have their recommendations on how to fix the issue, one of which is a lot of 404 pages so I need someone who can fix this issue and get my site content showing up in google news again. I can provide access to webmaster tools and the e-mail content highlighting what is needed to fix. Thanks.
