Hi!
My name is Keith and I am US graduated mechanical engineer. You can see my profile for some of my academic work, but I also own a start-up graphic and web design company and have written multiple business plans for other business, as well technical articles, manuals and other documentation.
I will be able to give you my full attention on your business plan and ideas for your company, and although I do not know the entire scope of the work, I believe I can be extremely beneficial and will not leave you unsatisfied! I only do quality work!
In terms of the # of words as you requested, my bid of $100 will cover well more than 500. I am assuming ~2000 words or more depending on how in-depth the project is, and whether or not you are able to provide other projects.
Thanks for reading.
