I'm asked this question quite a bit:

Should I market my new website with PPC advertising, or should I focus on natural search optimization and marketing?

The answer is: You should take advantage of both PPC and SEO. PPC marketing will get you tracffic quickly, allowing you to test the effectiveness of your new site and get an idea about your conversion rates. When you have that data in hand, you can then reduce your marketing costs by shifting some of your efforts to search engine optimization (SEO).
