Marketing , Sales related issues
A little more information as to where you are at with your business and short term goals may be helpful to offer more direct advice, but initially I would stay start with the goal and then reverse engineer the campaign. If it is your first marketing efforts, I would also recommend spending very little to no money. There is an art and science to marketing and you can spend an incredible amount of money with no impact if you don't know what you are doing yet.
Your next step depends on your current step. That's somewhat like Start Your First Project.
What marketing research have you done already (if any)?
Well, as @Clay said, you start with research, not with a list of tactics. Make a list of your assumptions. Test each one of them individually. Develop a strategy and then validate that strategy with your prospective customers. Your research should inform your strategy and then you can determine what tactics will help you deliver on that strategy. Remember, marketing strategy comes BEFORE product development. If you have your product already and you are just now considering how to market it, you went about things backwards. Stop all else and do your research. Your audience will tell you exactly what your product needs to be to make them choose you.
