Translation of pricey in Spanish

I usually charge 15 dollars per hour, but I don't care very much for the hourly system. I can also help with corrections and suggestions, but only if the original text is a serious translation and not an automatic one.
I think that working with you in this case would be just by Skype because it will be 8-20 sentences per month and always spontaneously like today's message which was 'Another five days until the weekend...'
I'm learning Spanish, I have been dating a girl in Peru a few months ago, but, unfortunately, she speaks only Spanish. If everything goes well I will move there! For true love I'm ready to do a lot.
