Business without license

To whom this may concern, Thank you for reading my request. These people are running a business since 7 months illegally without a license & I've been waiting for them to be shut down. I understand the city is busy, & you might have not known, so that's why I'm saying something to you. This is a public nuisance in our neighborhood . This must stop.! They have signs on Atlantic Avenue and S. Nashville Ave. on the weekend they put up lawn signs also. Thank you for taking care of this matter
