Market gardening means that you are producing for customers. To ensure a continuous flow of income, you first need to confirm a continuous production. For this, it's essential to plan a production schedule for your crops.  Plan your production schedule by taking into account what you intend to plant, the number of days your crop will require to reach maturity, and when you plan to take your produce to the market.  You will know when to start planting, which is usually according to the last spring frost date and the first fall date, which plants will be available for seasonal production, and which plants will be available all season.  The primary goal of having a production schedule is to enable the smooth running of your garden production and meet market requirements at the same time.
