Thinking outside the square... In Australia we do stands at Home Renovation Shows, Landscaping and Gardening Shows. We also have created 2 websites, and are currently sorting out our keywords, so we can double dip when people search. <br />Also, we are currently expanding our presence into the Architect/Home Builder field to get these guys to design and build homes to suit our needs, and then specify our product for the new home. <br />Others might have some more areas that they do other than the obvious Pool Builder/Pool Shop method of refferals.<br /> Maybe contacting Real Estate Agencies to have brochures for people if they buy a house with a pool that does not have any solar heating. That has not worked for me personally (I tried but did not get any response from the 3 agencies I tried), but in different markets, different things can work
