How fast to make 5K/month

Hello guys, would you have any idea how fast it takes in average to hit 5K/month in benefits ? (Pre-taxes) Idk if there are averages or if it just about how skilled you are in marketing, etc.. I ask because I feel stuck rn, I have a window cleaning business since last year that takes time to get traction, especially in this season and I wonder If I could start dropshipping as a side hustle with the knowledge I have from my current business in website making, Google ads and the legal part
