Hi, firstly you're not alone when struggling with the financials part of a business plan... I most certainly did.
What I suggest is getting a second hand copy of Timmons' "New Venture Creation" book and look at (and copy) the Business Plan template.
You can pick up this book for $5 via Amazon (http://www.amazon.com/New-Venture-Creation-Entrepreneurship-...) and IMHO it'll be the best $5 investment you can make to assess your idea and build a 'formal' bplan (aka what an investor or incubator/accelerator will most likely want to see).
The template is quite comprehensive but just skip the bits that don't apply to your opportunity. Follow Timmons' examples as to how to work out the financials (and copy the example layouts given).
Good luck, btw read that book front to back... it's one of the only entrepreneurial books that has stood the test of time for me and I have gone to it through several different start ups.
