Am I shooting myself in the foot by bidding too low?

Hi everyone. I did a search for other threads like this one but couldn't find any with the kind of information I'm looking for.

I am new to this business and I've been writing for a company which seems legitimate, as far as my experience and research show. Generally I've been bidding about $12 a page per project, and after several hours of research on a frustratingly vague assignment with no writing done, I'm starting to wonder if I'm undercharging. (There is also the possibility that I'm being too much of a perfectionist about writing these papers.) I have no idea how much this company charges customers or how much their other writers usually charge per page, and I'm afraid that if I raise my bids, they won't give me work anymore.

Any insights or advice from those of you who have been at this longer than I have? Thanks. :)
