Audio processing required - Remove background noise from interview audio files

I need a freelancer to remove the background hum/noise from the two links below(wav files). These are two interviews that were recorded with a bit of a low gain and I need them to be clearer for use in a video i am editing. Don't worry too much about the guy asking the questions its just the audio of the responses (which are a bit louder as the mic was closer to the person being interviewed). Anyone who can noise gate or process the audio and send a wav file that that has the words of the interview with less of the humming and noise get the payment. simple!
