Problem raising funds through VCs for app development
I'm an artist that did a concept design for one of my mobile app ideas, and I've met a company/developer that can develop the app for a certain price quote, which I just can't afford now. Due to my lack of the funds, I've reached out to about forty venture capitalists(VCs) through the LinkedIn site, but have been unsuccessful to raising the funds through them. Even though about four VCs showed interest to my app's concept and asked for my business plan etc. they seemed to lose interest when I sent them my business plan without any explanations.
I'll appreciate if you can advice me on the best possible way that I can raise this fund through VCs/angel investors to enable me develop my idea into an app that can be sold at the app store.
