My Kua and my office

[myfs_42008]

Hello My name's Kate, my Kua number is 8. I am the owner and a teacher at a language school. The premises where I rent my office was built in June 1987, there is a river flowing in front of it and some trees; the building number is 4 and the office number 23; I have some problems with attracting customers. Can I do anything about it , hang a windchime near the door (facing N, or put some plants? From what I can see with my limited knowledge of FS the building is earth element (three-storey white, square) and the surroundings are fire and wood. There is a bit taller building behind. Please help
