50 short audio clips to be gently enhanced sound balanced

I have about 50 clips (20 secs - 1 min each.) Some need gently enhancing - (emphasis on naturalness rather than hard denoising) some background atmosphere is a good thing actually. Then a few need clicks and bumps need attending to. Then they need matching (decibel equivalents) so that someone listening does not have to adjust for each.

Please note - there is no need to enhance every clip - some are find and just need equalising against the others. I repeat that we are looking for a natural sound with a natural background not - a hard denoise. I will be including a table of what I think each clip needs.

Speed will be of the essence. I will have most of the clips ready to send tonight (Tuesday) UK time and looking for turnaround in 24 hours. So please only tender if you know you have the time.
