Startup Idea : Selfie Drone

I have an idea but I have no idea how to execute it. I'm well aware drones are only growing in popularity and profitability, and I'm wondering how to tap into it. I'm also aware there are already drones out there capable of my idea, however I think it could be integrated within the current market. So I'm thinking of designing and manufacturing my own line of drones. Ideally, they'll be:- Small, compact and easy to carry- Feature a hover mode / follow target mode (to enable easy selfie shots)- be affordable, yet durable and high-quality- visually appealing- Have a respectable battery lifeThere's more features I'd probably implement, but as a whole I think the concept of a cheap, transportable drone which you can pull out, control from your phone or control pad and take perfect selfies within moments, is something that could be successful. Anybody got feedback, suggestions, viability, costings etc that might help me make a more informed decision? (Or want to get involved?) Thanks :)
