First, you might learn the basics of grammar and spelling. I would never hire you as a proofreader. Your question contains several errors. If you are a typical teacher, no wonder the kids today have no skills.
Your question should have been worded:
"I'm a teacher; how should I write a resume for getting a proofreading job?"
Note that "I'm" and "I" should be capitalized.
Note that there should be a semicolon, not a comma, following "teacher".
You don't "make" a resume; you write or compose one.
Since you used "proofreaders", why didn't you include the required apostrophe?
(Note that there is some controversy about where to place some punctuation marks relative to quotation marks. I am using my preference here.)
I am just an ex-techie, and I obviously can write better than you.
Take some remedial English grammar courses. Pass them with an "A" grade, not the "D" you probably now qualify for. Then, and only then, perhaps you could consider applying for proofreader jobs.
