commisions and what's the right price?

Okay so I can draw somewhat and so can many other people out there. Lot's of people do open commission work. Writing, drawing, coloring.

What I want to know is what do you guys generally think is a proper price to pay for this kind of thing?

Were I to actually charge people to draw stuff and agree to do something for them the following is what seems appropriate to me :
5 bucks gets you a page of doodles basically. 3 or 4 sketches/ poses pencil only
10 dollars gets you the above plus I draw a better fully detailed and inked version of 1 of the sketches, scan it in and clean it up
10 dollars also gets you a 1 page sequence of no more then 6 panels pencil only
20 dollars = 1 page fully inked and cleaned up
for 30 bucks I'd give you a sketch page, black and white pinup of 1 sketch and a single fully inked sequence page
Finally if you wanted a full on comic booklet/short story thing made up and you had a script as well as a rough visual outline :
100$ would get you a 12 page black and white uninked comic book
150$ would get you a 12 page black and white inked comic book
and 200 $ would get you 12 pages b&w inked and digitally cleaned up
Add 5 dollars per page if you had no visual outline and 15 dollars per page if I had to come up with a script as well.

These fees would be for artwork only, I'm not much of an editor so the text would be left as placeholder word balloons with hand scribbled text inside. I have a poor selection of fonts on my computer so you'd get better results as a customer of mine to take my finished artwork and pass it along to someone who is better at the post production process. The smaller jobs I'd happily do essentially "pay when the buyer is happy" 20 dollars and less basically would get previews of the work in progress and could suggest things. It'd also be up to the buyer weather or not the image is shared with anyone else by me later on.

I wouldn't sell color, if someone wanted me to color I'd try it but I don't feel right charging for something I don't feel I"m any good at.

Now idono, do those prices seem fair or am I asking to much? This isn't even so much a question of my work quality either, I only want to know moreso if generally the above prices are good.
