Hello everyone, this is my first post on here so apologies if these questions seem somewhat basic or have been answered in another format elsewhere.

As a bit of background I am a property developer with sites overseas(Bulgaria and Spain). I am often asked if I would market property developments on behalf of other developers and I would like to be able to do this.
Presently I have a web site that I update with Macromedia Contribute and that is the limit of my web authoring talents.

To take these other developments on board I will need to develop sites from scratch and with this in mind I have started looking at tutorials recommended on here and although I do have the time to increase my knowledge I am under no illusion about the amount of work I would have to do to just be able to put up the most basic of sites.

My question is this - I have just had a meeting with a company that wants to sell me a course leading to A Macromedia Developer Qualification after completing a number of modules.
The modules are:
Access advanced, HTML,css,Javascript programming,Dreamweaver and Flash,intro to XML,ASP.net,E commerce,then Internet Services Project Diploma,and CWDD.
So do I work through the modules via the tutorials available freely or am I kidding myself not enrolling on a structured course like this.
Thanks in advance - btw the course is around 3k.
