It is not a good idea to change the path from ur current skills. The job u have done and the course u chosen is entirely different from each other. Web development is a course and the contents of the course are basically for developer or the persons who r doing the same from their earlier stage. It is necessary, to know some or more knowledge on the same field. I am not going to discourage u, rather I am telling the fact. Certification and specially global certifications are obviously valuable, but u have to do that way which u know or working before.
Why r u not interesting in SAP course or Project Management course ! These r very good and lucrative. Of course money is the matter.
