Research writer wanted

I want a good research writer to write a book for me. The subject matter will be finance and negotiation based and this will be sold as a business opportunity.
I will disclose the format in more detail once relevant experience and suitability to the task is assessed. Ongoing writing assignments a good possibility for the right applicant.
Applicants should have examples of past work and samples of writing style will be essential. Expertise in spreadsheets and other programs will be of benefit to the application. Ideally I'd like this finished in a month or two
Thanks for bidding
