One key to getting "bang for the buck" is to move forward in small, carefully planned increments. Look for things that appear to add clear value towards achieving your goals for reasonable marginal cost.
Worst thing to do is to just throw money at the problem or use cost/money as the measuring stick. IE, the more expensive option is necessarily the better one. Guaranteed you will overestimate what it actually costs to achieve your goals that way. Many tweaks that have the biggest impact cost next to nothing or nothing at all once the problems to address are well understood.
