Unfortunately, you can't.
Based solely on the information you listed, today is July 14, and your birthday is in January. Lets say you are aiming for January 1. That means there are about 25 weeks left. If you work 4 days for 4 hours each a week for 1 month, then work 2 days at 4 hours each per week after that, you will have worked a total of
(4days x 4 hours x 4 weeks) + (2 days x 4 hours x 21 weeks)
64 hours + 168 hours = 232 hours when january comes around.
$7.25 hourly minimum wage x 232 hours = $1682 before taxes.
I couldn't do that, and I'm an adult with a good salary.
You might save enough for a down payment, but nothing like what you're saying.
