nah you are not good man, you need at least 10k per month for a third country people to marry..... just joking of course.
There are so many factors and personal factors to your answer let me give you some food for thought...
Can the money you make afford to make and raise a family? ( that's the point to marry someone right ? )
Do you have any alternatives if the business starts to fall apart? (backup plan, money sitting somewhere maybe in your pillow ?! )
How many hours do you spend for these 3k dollars, does it takes up all your personal time? Do you have spare time for socializing? Cause marrying means having time to spend with your family, money is not everything.
Can your business scale up ? For example start with 1 emploey and scale up to the point you are working less and make more. Work smart not hard!
Living in EU I could start making a family with 3k per month easy!!
