I am a native English-speaker, and I am very interested in taking this project on. I work part-time as an English teacher and I have experience in academic writing, journalism and proofreading published novels. As a result, my English is as close to perfect as you will find anywhere.
I've bid one dollar per product, but I can be flexible on this point once I see the products. I work quickly and can meet whatever deadline would be most convenient for you. Thanks for considering me!
