Translation of perky 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.
As mentioned in our conversation, I will send a more detailed description about all the other exercises. As indicated previously, I believe in your technical skills and in your talent.
If you are spell checking my letters, that would be great. I would then do the same with your letters. Can you please correct this email too? I thank you in advance for helping my Spanish.
