Hi..
I`m Peter, composer, arranger, audio-producer, experienced +30 years, audio-freelancer.
Your project description has no details - let start chat about "what exactly you need" -
1/ do you need audio-track/s/ with saxophone or clarinet ,cello, violin instruments sounds playing it? (I have "virtual sets" of instruments from Native Instruments, Yamaha, Roland AND I have in my team of coworkers professional musicians from philharmonic-and--opera orchestras for live recordings.. )
2/ amount of tracks + playtime of each or total audio
3/ music style of music you need to be produced using those listed instruments??
having all that - I `ll be able to set correct values (working time +money) in my bid, and bring you at the end right audio as you need..
