Man of many bad ideas,
Thanks for your comments, the real value here is the insight into the different methods (Arming Inventors with options and insight), of getting products into the market place, I will say the last 2-3 years have been hell for me, due to the world money markets but it is all starting to change.
from my personal first 6 new Inventions, 1 has failed (dumped at a low cost of $1,000-), 3 Licensed under assignment of Patent rights and tooling paid for by Taiwan manufactures, 1 sold outright and this last one still working on the Tilt Level, link below
http://www.youtube.com/watch?v=hCMA2pdiNGkI had 3 quotes in China for the tooling, $45,000- to $50,000- for the 3 different level sizes, 1200mm,900mm and 600mm
Last year I showed the buyer from the largest Hardware Chain, he said yes lets go through the process of knocking another Level off the shelf, due to that the Australian Importer wanted pricing, due to our market size here it is not worth it here in Australia.
Currently I am talking to a China Manufacture, the Tilt Level I am looking for the lowest price point option, I also know this new design could be placed at only $2- more for the say Standard plastic levels at retail.
So here I have the reverse problem, retail buyer says yes, importer say yes also, just trying to find the right manufacture, to carry to tooling risk at least, so I went more the traditional way, well partly.

My first Invention the Roofing Protractor below:

I always had the Mindset that I would not pay for Patents, so for 12 years it was a trade secret never made public, once I found the Taiwan Manufacture, we did the deal by e-mail, and I said for a bit of fun come and see me in Melbourne, guess what they jumped on a plane and spent two days with me, my Chinese business partner organized the License agreement, it was a very standard agreement with assignment rights also
I gave them 12 years work from me on a hand shake (all prototypes,the whole cot and cobudal), they signed the contract and returned 3 weeks after returning to Taiwan, yes I started to sweat about it 2 weeks in.
Due to my actions yes it has taken forever, 16 years from 25 August 1995 to Feb 2011 for Europe, but there are 9 Patents and they all have at least 18-19 years life left in them still.
I will start the final artwork for the Roofing Protractor and branding for the Dutch importer in the next 4-6 weeks with my designer, I also organised the exclusive distribution agreement with the Taiwan manufacture and Dutch importer for Europe,so with about 6 inventions, I am marching them all the way over the line to the market place and shifting the risks onto manufactures and importers, which all comes back to the level of interest in your new product once again.
My Sapper training in the Australian Army (5 years) has also helped greatly (Strategies) and past sales experience with different jobs and market researcher also for a year!
So this is a very tough game, getting new products to market and not going broke in the process.
