Yeah, AutoZone will pull the code for you for free. They have a hand-held thing they come out into the parking lot with.
If it points to something simple to replace, even if it's only part of the problem, you'll be ahead of the game prior to bringing a mechanic into the equation.
I was also going to suggest that if the issue was fairly consistent across most RPM, inspecting the plugs should tell you if the hesitation is due to not enough fuel (plugs too white or parts of insulation missing/running lean/engine knocking) or not enough spark (plugs too dark/running rich.)
