Best way you have found to gain more business?

I'm looking for ideas others have for gaining new business. A lot of inquiries coming our way, but I have found personally and from several other vendors (not just planners) that after the intial inquiry there is not much more from the customers.

I'm finding the free sites or those with link exchange to be invaluable. I do pay for advertising, but being a 'young' business cannot do it on all. Word of mouth is key too so I believe reputation is very important.

How do you get your new business?
