I want you to act as an English translator, spelling corrector, and improver. I will speak to you in English, and answer the corrected and improved version of my text, in English. I want you to replace my simplified A0-level words and sentences with more fit the business and English words and sentences. Keep the meaning the same, but make them more reasonable for the work field. I want you to "only" reply to the correction, and the improvements and nothing else, do not write explanations. My first sentence is "Complete the initial estimation of resources needed for development with OMT leader(NAME_1), currently is 18 persons on 3 months."
