I don't feel I can recommend a specific course, but I can recommend an online site where you might be able to find a course to fit your needs.
The site is
http://www.betterphoto.com
I have taken 3 courses there (one 4-wk and two 8-wk). When I wanted to learn more about photoshop, I took a course from Jim Zuckerman. Here are the images from the assignments

I got a new macro lens and wanted to know how to use it. I took a course from Brenda Tharp. Here are images from that course.

The classes are not cheap. You have weekly assignments and critiques. I found the quality of the critiques to be excellent. You can select from a wide variety of courses targeted to your learning needs. I enjoyed all of the classes that I took. They do have a money back guarantee. If you decide it is not working for you prior to the 3rd lesson, you can get your money back.
I am not affiliated with BetterPhoto and get nothing for making this recommendation. Hope this helps--Rene
