Hello, happy to bid on your job!
Would love to help you write a personal thank you letter, and can work with you to make it in the tone you want. Below are professional credentials for writing.
I do freelance writing, editing, proofing, and re-writing for individual artists and companies in the US, Belgium, and elsewhere. I am a native speaker of American English, an English teacher (CELTA certified), and a graphics design artist. I have been doing this work for some time outside of freelancer.com and can provide references as required.
I am available part-time (30 hours/week) ongoing, but can always push to meet deadlines when you need.
Thank you and look forward to working with you,
Katie Hoku Kirkland
