Translation of merciful 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.
Somehow, my email was not sent. There were even a few mistakes, but really only minor things, nothing really bad. I've already read some other texts that you have sent and are getting better each time.
Thanks for the connection request. What is your name and why do you want to learn Spanish? I'm flying to Mexico in August. There I want to study Spanish and learn ... Either in Mexico DF or in Cancun.
