Funding your idea is always very difficult especially in third world countries where support structure for entrepreneurship is low.
One very important information you need to arm yourself with when seeking funding is; knowing the exact amount you need to raise. You can’t just have a vague figure or rough estimates if you are serious about executing your idea. You also need to attach your estimates to a tangible goal. The goal could be to develop your product, acquire assets, expand your market base, increase profits, etc. That is how you can figure out how much money you need to raise.
