GL with getting $300 a month, your going to need a lot of luck to achieve that and don't forget your also going to need skill.
I am no expert but reading on here has given me a lot to think about on how I play poker and my game has improved immensely. I used to play a lot of freerolls
but just could never get ITM but since I joined here I have started to get some decent payouts. As you are new to the game I suggest you read the strategy's on here and other sites, there are a lot of good articles out there if you are willing to do the research. I hope you get your $300 a month and if you do share your success with us
