Having the prices in journals could help with costumers, since at least they'll know how much you charge.

i do post the prices in the commission page. tho im not sure if everyone who visits my page even sees it. since i see a lot of people using the journals.

Some people I' sure visit it, but yeah it is a bit out of the way, but that page is at least displayed in big letters. I guess, if not on a journal itself, then maybe you could direct people to the commissions page to see your prices?
