There unfortunately is no silver bullet type of answer for your question, but there is some things that you can do to help you achieve your goal.
Most importantly, study and get really good at 6-card PLO, this will take time. away from the table study and at the table practice. Get some type of software to track your progress, review hands, and keep information on other players.
Play more than 3-4 hours and as many tables as you can if possible. Work towards increasing the number of tables you can play without effecting the quality of your decisions. This will help reduce your variance and amplify your rate of return (hopefully positive).
Don't expect consistent and stable income especially if you are a beginner, you will experience downswings and bad beats regularly. Lowering your variance by increasing volume will help mitigate this.
Assuming you are starting from 0, get a few hundred or a thousand hands in to get a baseline of your current winrate and your statistics of play. Identify leaks, issues with your mental game (tilt, confidence, etc.), evaluate your skill with multitabling, etc. Study and work to improve on these issues both away from and at the table, once they are fixed then rinse and repeat.
