Those are ridiculously low fees...if you don't value your work, then who will? Don't sell yourself short.
In my town there are a few photographers who are quite popular among the middle-class clientele (I say this so you don't think that everyone in LA is some kind of millionaire), and they charge $250 for a sitting of about 1 1/2 - 3 hours, all digital, on location...small proofs are made by a service like Miller's, and prints are ordered after seeing the proofs. If I recall correctly, a 5x7 is $65, and 8x10 is $105, an 11x14 is around $150. Average order plus sitting grosses around $600.
The photographer's time encompasses the first meeting, the shoot, post-processing, proof presentation and final print delivery.
