Wise,

You are probably doing the best thing. Overall set a base price on each resource that you have whether it is bundled or considered a single solution then set your margins on top of that. I learned early that competing with people that charge pennies for a dollar service is not the market I want to be in. There is always a buyer for your product, the support behind the product is what people are paying for. Keep up the good work and choose your clients wisely!
