If you have a vehicle of some sort, whether a car, truck, or van, why not use it as a travelling billboard? You can start with magnetic signs, they are very inexpensive and if you do a lot of driving then a lot of people will see your signs. Now if you have a very nice car and your worried about the finish then what about plastic letters adhered to your window(s)? This can be very effective and very low in cost but you gotta think about this, when people stop for traffic lights, railroad crossings or just for a stop sign their eyes will scout the area. This is a very common thing that almost everybody does. Did you ever stop at a railroad crossing and see these signs that are stuck in the ground with advertising for a mortgage company? They're not being put there because they don't work.

Business cards, another low cost advertising mechanism. don't just put your name and phone on them put your website if you have one, your email address, and a one line description of what your business does. Now the next thing that needs to be done with your business cards is a visit to your local book store. if you are a Real estate agent or a mortgage broker then go to the section where all the real estate books are and put one of you cards in the bindings of each of the books. somebody who wants more info on buying a house or obtaining a mortgage is going to go to the bookstore and start looking at all the books on this subject. then they will see your business card. If you sell to small businesses then put your biz cards in the section where people go for books on business.
