Guys, I need your help, I wish to know which training centre provides WSS or SharePoint application development training, such as learning to use APIs to develop / customize web part, make change of CSS, use “caml” in SharePoint, email alert etc?

Note : hoping for level 400 kind of training (more on hand-on development but not introduction).

We tried some of the local training centre, but those courses offered is not what my boss wants.

Your reply is much appreciated. Thanks.
