I would approach local graphic designers. Look at their portfolio's - see what quality they can produce and short-list them.
Have a good idea of budget in mind.
In most cases crowd-sourced logos won't deliver a great result, as many of the participants are not trained or professional designers, so be wary of that over working with a team or individual who knows their onions.
