Need to hire for micro-controller programming, where do I go?

I'm designing a display piece that needs to be lit with what I'm imagining to be a small cluster of LED lights, maybe something similar to a puck light, but I need to custom program the light sequence. I've recently seen a video on how you can use an arduino to run custom LED light programs, but I have no such programming knowledge and I'm not sure using an arduino, necessarily, is the only way to get this done. I need to contract someone to write an arduino program to run LED lights and teach me how to put together such a light system, as well as flash the program to new processors.

Where should I go? ... On Fiverr or elsewhere on the web to request this kind of job?

Thanks
