"I posted it, and my friends posted it. I had friends as far as Oregon asking how they could contribute," said Kim Trent, Rhonda’s childhood friend.
They’ve also received donations from people around the country via a PayPal account.
Joshua’s first customer was his next-door-neighbor Robert Rucker, 60.
"The city really needs all the help it can get, so I wanted to help out," Rucker said. "Somebody needs to try something; the adults too."
People can donate to the City of Detroit by visiting the city teller on the first floor of the Coleman A. Young Municipal Center. The money will be added to the city’s general fund unless a particular department is specified.
Joshua plans to send Detroit Mayor Dave Bling a note with the donated funds stating:
"Dear Mr. Mayor, I'm sending this money because I hear the city is broke and I'm hoping to raise $1,000 or more so we can have lots of money, so we can cut grass and fix the water fountains in the park."
During the first few hours of being in business, Joshua made $69.
