I can honestly say that I am nine years into doing exactly what you are trying to start. I have learned a lot and wish I could go back and re-start knowing what I know now.
I have spent a LOT of $ and many years acquiring equipment to make my own stuff. I should have done things differently.
Find a good business manager and make sure he understands what you want and where you want to go. Then listen. The job is too big to tackle yourself if you want to do it properly. Do what you do best and find folks that can fill the gaps. Find a manager and a marketing person and find a way to engage them in your vision.
What the product is absolutely irrelevant - business boils down to management and more importantly - marketing. The product and market is important to the marketer, of course.
After nine years, I am just now where I wanted to be eight years ago.
It doesn't matter if you are making plastic vomit or women's underwear - the business needs sound management, clear marketing direction, good financial management and guidance. Finding all of these in one individual is extremely difficult.
In my case, it took me a long time to realize that I am good at design and good in the shop. I suck at managing my own company - it's just not my strong point. Perhaps you are more skilled. I now design and stay in the shop - someone else runs my company and calls the business and marketing shots. This is what I wanted I just didn't know it when I began. Sounds odd, but it's working for me.
You need more than money - you need experienced help. Realize it as soon as you can. Also realize that as unique as you think your idea is - its success will be realized using standard business practices that apply to any product. Nothing is really all that special about your situation or your product - whatever it is. Try to remove your emotional attachment to your idea - this is a very, very hard thing to do for nearly any entrepreneur. I know it is/was for me.
