I recently created a business plan for a venture in the US so am familiar with this. I can help you create your plan and also do any research required. I have experience of writing 4 business plans in which 2 have sourced funding and the other 2 are still trading.
Is it possible I can learn more about the venture itself before bidding? I understand it can be confidential and willing to sign an NDA.
I look forward to hearing from you.
Keep in mind that you have more chances to win a Job with Case Study as fewer Sellers will send a proposal. Moreover the Buyer has already paid a fee for it, which shows that they seriously intend to award the Job.
