Howdy!
I believe you're looking for a freelancer to answer calls with American accent and GUESS WHAT? You're now looking at the right person. I'm fluent in English and for me, American English slang is just a piece of cake and basically some American English slang is readily embedded in my mind. To add, I'm especially thorough in choosing my words so no grammar mistakes or errors shall be done when i'm providing my service.
If you pick me as your proofreader, I'll assure you 3 profound qualities:
1. Promptness
2. Professional
3. Delicate
Let's say if you are convinced enough, let's just promptly seal the deal! I am looking forward to cooperate with you already.
With regard
