My thoughts are:
1. If there is a genuine need for this in the home, then what is fulfilling the need now? How is it being done? Is someone really going to be willing to pay to have this role or function fulfilled. Maybe it’s time to do some market research. Reach out to a load of your facebook friends and ask them if they’ve ever needed xyz – or how do they do xyz.
2. You might want to approach some product designers for a bit of high level advice. I’m sure they’ll give you 15 minutes of their time for free to help you understand the process you need to go through and the costs associated with getting a product to market.
3. Figure out how much of it you can do yourself and look to your close friends and family to see if they have the money to help fund it in return for equity in your new business.
