There is no fee to you unless you sign an "exclusive buyer broker agreement".
You can contact any agent without obligation, who would happily show you properties. However, should you choose to work with just one agent, get recommendations from friends, relatives, co-workers etc. You can also look at MLSLI, TRULIA, ZILLOW etc. to find experienced pros in the area of your choice. After seeing a few properties with that agent if you don't feel right, switch!
