After getting increasing frustrated with my stalling career, I am looking at getting into the web development / web design industry.

Can anyone suggest a good training course or training company ?

There are so many to choose from, I'm not sure where to start.

In a previous life, I was actually a desktop support analyst so I do have a good understanding of IT.

Khan Academy is an excellent free website. The coding section is fun and visual, could be a good place to get started: [Link]
