IOT project that will require an Arduino and HELP :)

Good day forum.
I am working on a prototype of a sound and light therapy bed. I will need to incorporate two different LED light sources, music, transducers and an amplifier for the bed. I have been researching how to bring it all together to and have reached out to businesses and people that I thought may be able to assist me in setting this all up. I lack the professional technical knowledge to do this by myself. I am having a really tough time figuring out what type of business/professional to turn to for help. Do you possibly know what type of business I could go to to help me bring all these components together? If you're able to help I would greatly appreciate it. Either way thank you for your time. Ed

Doesnt narrow the field much!

Why cant you use readily available components - eg music player, sound to light unit?

Can you provide a sketch of the arrangement you are planning so we know what kind of LED lights you would need, and an idea of the power level? eg

If its a bed would the light be displayed above the patient - maybe with a projection system?
