Marketing / Advertising Question

[GeeRawkz]

So in an attempt to revamp my company's financial advisory/consulting marketing strategy for our services, which includes but is not limited to providing strategic, operational and financial management services to investment banks, private equity and small and middle-market companies.

I was wondering if anyone has come across any good marketing/advertising groups that help you reach out to your target clients or any tools/strategies that could aid us in achieving this.

Any help or insight would be greatly appreciated!
