Those prices are very reasonable, if you put a fair value on your time, and include a fair price for use of the tools, machines, etc that you already one. Remember you have to design, shop for, as well as arrange pages and paste the stuff down. You may have to interview the person and arrange the photos in order, get enlargements made, etc. You have cardstock, patterned paper, adhesive, embellishments, the use of your tools and cutter etc. If you are running a business, all those things need to be taken into account. Materials alone are going to be 5 - 10$ per page, depending what you do.
I just made a 12 x 12 80th birthday album with 30 sides. I spent ~10 hours interviewing, several hours planning the scheme, I had to buy design software for my cricut in order to execute the title page I had in mind. I had photos reprinted (photoshop time, scanning time, upload to snapfish, order, drive across town to pick them up time) 2 x refills, 2 atg refills, 90 sheets of cardstock/patterned paper, a nice leather covered album, extra page protectors, etc etc.
Probably $150-170 total materials. 60-70 hours of total time.
Until you stop to evaluate what you actually use, you don't realize what you've spent. If I was selling that Album, it would be $900, and that would be very reasonable. $900-$160 for materials = 740/70 hrs labor = ~10.60/hr.
