Hello, my name is Humberto Valle, one of Arizona's best strategists. Here is my feedback/advice on your question:
Have you created a business plan? How about a marketing plan?
As you create either of these two, you will/should find what values are essential for the prospect client and market as whole. Who your competitors are, what they offer and how they offer it. What distribution channels they have in place, their price points and margins. Even if you don't think is needed, I want you to track back and don't skip these two plans. Even at their simplest, they can provide you with a lot of insight that you would otherwise have to wait until a particular situation forced you into it. Do research, write it down, write down possibilities and laymen instructional for how to achieve them.
When it comes down to it, never ask yourself, what is the least amount of money I can spend in marketing. Investing in the right marketing channel is an investment not an expense, particularly when done right.
Feel free to give me a call if you need help with your plans, finding the right marketing channel for your type of business, setting a budget, etc. Feel free to google me as well :)
