I agree with Dan. I also think that in most situations it is better to try "cheap" methods first. You need to know what you are up against before you put your chips all in. Many times using cheaper or free methods of marketing can spark new ideas on how to tweak your products or services. I always say that if you are not walking on the edge then you are taking up too much space. However, I don't like the thought of walking tight ropes without nets either. This is especially true for your own self-esteem and keeping your support system (family, friends, and investors) on board and your momentum going forward.
The number one place you should start is with making your website full of interesting and useful content and using a physical address for Google and Yahoo places.
