I have personal experience of starting a niche record store with a friend. We were both tired of the music we wanted not being available and decided we'd do it ourselves. Neither of us had any idea about the music industry. We both put in $500 each. Every dime of that was used to buy the initial inventory. We had no money to have a website built (circa 1999). So I learned how to use MySQL and PHP and built one. During the years we ran the business, there were many conversations with artists and record labels. We sold compilation albums where other people licensed individual tracks from labels and arranged them together onto a CD. We even had several discussions about starting our label, but stopped short of that.
