If you have very little in an advertising budget, then try to no cost or low cost advertising first. You should try the various means of promotion and find out which is the most effective for your type of product and according to your advertising, marketing, and promotions budget.

Once you find the most effective selling methods for your products, then you should focus on these. Of course, you can continue the other sales methods, but most of your sells work should be in the areas in which you are most effective.

Should you want to work in the other areas of sales and promotions, then you can hire according to your budget experts in these areas. For example, if you're most effective in writing classified ads for online and print markets, then you should focus on this method of sales.
