Google Feed Product Insertion help

We have product feeds that need help. Simple going over over the feeds and help us make sure they get inserted, I understand that all mya not get inserted and for that we can take care for the errors on our side. but we need to see that they insert some, or most successfully and we require a cron job set for nightly updates at 4:00 a.m. PST. Thanks, Only those that know how to handle the Google feeds and with Zen cart need apply with the lowest quote win. We don't want to hear about your past unless it directly relates to our issue
