Go with your 2 best skills and find customers that you can immediately impact by one or two of those skills. Once you get in the door and make an impact you can then "cross-sell" some of your other skills and continue to bill out your time. Try to identify customers that might need, for example, lamp or api help (assuming many do) and start small to then grow your consultative skill sets to other areas of the customer's business. I made it sound easy as pie but narrow your focus and get your hands dirty!
