Looking for an Audio Engineer!

Can someone give me tips on cleaning up a 24Bit WAV file with a sampling rate of 96k?
- to cancel noise reduction
- eliminate reverb
- make voices and spoken language stand out (the conversation takes place in the stairwell)

Made a thread on /b/ and got some help. Want to see if you guys could provide me with more. These were the tips given:
>Audacity is a free program that should have noise reduction plug-in that's half decent. Reverb is very hard to deal with, especially without the proper tools and to my knowledge there are no free de reverbs that exist, there's a little bit you can do with selective subtractive EQ to help but not with the amount of reverb you get from a stairwell
>1st thing would be to cut frequencies. take a look at where vocal frequencies lie. i would do some extreme cuts. then, i would probably change the track to mono. then compression. i would use reaper to do all this as it is "free", and has all the tools you may need.
>another thought: i would also take a section of the space where vocal is not present and analyze the frequency. more frequency cuts there as well.
