I can answer your general question about finding a "full time" Realtor. I will leave the local sales part to someone in your area.
You can call the agency, or agencies, who do a lot of business in your area. You can determine this by viewing property on Trulia, or on your choice of sites, and seeing who shows up most. Call either an agent who advertises on these sites or call their agency and ask for the "Designated Broker". This DB will be able to connect you to a Realtor who works your location.
You may want a listing agent who specializes or, better yet, a Buyer Agent who also lists property. Once you list your property the job will be to find a qualified buyer and either should do the job for you.
Consider, of course, that you have a listing agreement with an agent now and will need to wait for that to lapse before moving on.
