Assuming your product has a market, start with a patent search b/c somebody else might have made it already

Next form your own company
Next narrow down the manufacturing process including factory, tooling cost, suppliers of raw materials etc.... so you can get a test batch made. While doing this contact possible suppliers, resellers, industry professionals etc.. and do the whole website, press release etc... to let people know about your invention
Once the first batch comes through you should start sending out samples with pricing, availability, company info.
Then make $$$
