Does anyone know what the average price is to be charged an hour when you create a website for them. I've been using 20$ an hour as i have no clue what the real price is. What do you think? is it good. what is the avearge hourly price

All depends realy. i'm not sure that's their's a true bareme.
I know that years of experience pay, the longer you have been doing it the more you can ask, i've been raising by 5 dollars a year these last 3 years, just as an example

i ask for 20 euros an hour for whatever work i do on the net, it's a little more than 20 dollars but then again i don't design websites so...

I mostly see people who offer a total price for a website and that regardless of the hours. it's quite expensive but it is a lot of work so...
