I'd be happy to help you set a nice mood for your event by providing the music. These are some of the formations that are available:

Saxophone Solo
Duo - Saxophone with Bass, Guitar or Piano
Trio - Saxophone with Bass, Guitar / Piano / Drums
Quartet - Saxophone with Bass, Drums, Guitar / Piano

Bigger formations are also possible, for example with more horn or a vocalist. Another option is to have Duo, Trio or Quartet with Vibraphone, which will come at a slight extra cost because of the logistics.
If you couldn't find what you had in mind, please let me know so we can arrange for it.
