Creating centers of influence and referral sources

Hello, We recently established a small advisory firm few months ago to provide financial advice to high net worth individuals, business owners and professionals and I need help in establishing a strong presence in a fairly competitive, mature and saturated market. The best and easiest way is to attract accountants and finance brokers to refer their client base to us and need some help in getting those fairly protective professionals to see our value and what we could bring them and their clients. Any help/suggestion would be much appreciated. Daniel ednesseimATgmailDOTcom
