Hello,
I offer my services in writing copies for the subjects given. In my past I had written blogs thereafter I got involved with software development, thus could not write more. here's the link for one: http://inside-aspdotnet.blogspot.in. This one has two articles.
You have already given the number if words preferred, thus I would stick to 250-300 which seems enough or a few more words. I would like to k ow about your preference in the structure of the copy. I would, however, give you a structure to follow for each page, so you may give a go ahead and I will do so. Before that, I would like to know if you like a list down method or simple paragraph method for the pages.
Regarding the research, I would do a Google search and write a genuine unique copy for your pages. However, if you have anything on all the subjects that I can go through for research, that would be preferable.
I would be charging $600 per copy with good reviews to me. I hope that is fine with your company.
Please reply and contact so we can talk more on the subject.
Thank you,
Manish
