KickStarter Piecemeal Businness Funding
If you want to start a business then go whole hog and ask for the full amount you need or go home. It takes hundreds of thousands of dollars to fund a product from idea to final production and only asking for part of that is a sure sign that someone does not know what they are doing.
If you want someone else to pay for your little project that's fine but have a clue and find out before hand how much something is going to cost. If your wanting funds for a creative work you have a much better chance of having a positive outcome but if your working toward a product then get an idea of how much it is going to cost from start to finish to fund it.
Don't ask for a few thousand dollars to fund a product when that is only going to cover the first sample piece, you are going to need tens to hundreds of thousands of dollars for that first production run. If you don't believe me use the internet to search for it, you are going to be surprised at what you find.
To give an example that I found a die part for drinking cups cost about $60,000, figure out the math on how much it is going to cost to make molds or production equipment for your part based on that.
