I will suggest SOCIAL MEDIA is the best platform to promote any sort of business.
Please do research which social media site getting higher traffic,conversion rate.

It should be depend upon Business owner basically but as per my perspective it depends on type of investment. mean to say if investor is angel go for lower one based of fund raise by him/her.
And if investor is active issue twice of Angel investor.
