Hi...
after checking your audio - it needs denoising, dereverb and bit of EQ + compression ... All can be done by me with professional postproduction tools from Izotope, Audition, Sony.. as I have and use in my studio..
let`s talk about details as split point/s/? and few small things..
I place 'bit higher bid, because it is long playtime audio = needs more time to take care about all - this we need to chat too
