if u think about it......how many people are gonna use u all year every year forever?
then think of how many will use u twice i.e 2 blocks lasting x amount and costing x amount... not many
so u have to keep advertising to keep the 1 timers coming along and every so often u will get repeat business .... and someone may even come back a 3rd time....
all in all i cant see you building a client base and never having to advertise again....
u will constantly be chasing new business.....
