Its almost always through personal connections or word of mouth/referrals.
The primary concern for small to medium business is if the consultant being hired is actually capable of providing the service they are claiming to provide.
Hiring someone off of an online ad, cold call, etc. is just unnecessary risk. They'd happily pay more when they know that the output is going to be what they expect.
I strongly suggest you remove that. It's one thing to get inspiration from another site - another to completely steal someone else's work.
