How can I make 600dollars in 3 months or less
Thats only about $45 a week for 13 weeks.
Offer your services to neighbors - mowing lawn, weeding, edging flower beds, petsitting... babysitting, mothers helper... there are lots of moms who could use a break from their kids for a couple of hours, take them to the park, for example.
Start with people you know, tell them what your goal is, and work outwards from there. You could end up with your own small business!
