Vinyl Records, cd, music related. To establish a record store

I plan to revamp the music industry which recently many went bust such as Speedy, Rock Corner etc. I’m a music lover and reviving this business had always be my plan. I need to have a good business plan to go for crowd funding. Due to the pandemic I’ve lost my job as a company manager and I feel it’s time for me to start my own business. I’m now 57 years of age
