On first glance it's very much focused on Christian literature, mostly geared towards homeschooling. Not saying that's bad, of course! Two books I've come across are published by the founder of the company, whether they've published anyone else's I'm not sure yet. The book "Information in a Nutshell: Writing and Publishing" looks promising and not too bad priced, but not so sure yet.
All in all, unless you're looking to write for Christian homeschooling, your book likely won't find a home here.
EDIT: there are no clear submission guidelines, though she speaks of having clients. From the looks of things Felice Gerwitz (owner of Media Angels) has no publishing experience aside from getting her own books published.
