how to get customers? already had one business failed

change email to more proffesional one. at least your real name at gmail.com or get hosting service with your name at your business name.com
you have one car on site. maybe get couple friends and family cars and do wash and wax and do detailed pics
describe services and steps with pic examples of your actual cars. dont take any stock photos or photos from somebody else

maybe adjust prices for now. wash and wax 150?
