Old Recordings, Remastered

I have some old recordings of family from the early 60's, singing mostly. I am currently trying to clean them to the best they can be, but I am limited with my knowhow of audio to some functions within Audacity. And so I wondered if a professional like yourself would be the best option.

There are 30 tracks totalling 1 hour 5 minutes and 22 seconds.
Many are under two minutes long with a handful being between 5 and 14 minutes.

I wondered if you could quote me a price for the above if you are interested.

Many thanks.
