If you actually want to help your clients, instead of selling them on bogus, inappropriate solutions (which, with your attitude and lack of knowledge, I guarantee is what you are doing to your clients today), you need to start actually learning the fundamentals of your field. If you think that learning is "wasting time," then you are not learning, you are, indeed, only "wasting time." I am also a consultant, have worked with all the languages you listed, and I say the above to help you, and other people who consult, and me. Consulting is all about having a very solid knowledge base, continuous learning, and professionalism (which, BTW, includes basic writing skills, like capitalization). Attitudes like yours are why consulting engagements fail, and why consultants get a bad reputation. That only makes it harder for all of us to get work.
