How to acquire $3k in 3 weeks, legally?

[SirFelixCat]

So, something serious came up and now, I'm going to be $3k short at the end of the month. Outside of a traditional personal loan (credit isn't the greatest), how could I go about making an additional $3k by the end of the month? If there was another loan, I'd have the money to pay it back by the first week in July...I'm a uNL grinder, so poker isnt' the whole answer and I'm going to keep it legal. I'd appreciate any serious help/responses as this is a real trying time now in my house. TIA
