$150 is a lot for something you can watch YouTube videos for, and for something so basic I doubt people would really acknowledge it.
.Net, Orcale SQL.. perhaps, but I am not sure about JS and CSS. I think the best proof that you have the ability in web development is a portfolio.
Just my thoughts, but if you really want it and consider it a investment go for it!
exactly what I was thinking
Yes that's what I'm doing. I'm going through CBT Nuggets: Beginning Web Development at the moment, I know most of it but been a while since I touched it. After that I'm not sure where to go to get a more advanced understanding of the technologies. TeamTreeHouse looks good but will it cover enough for me to make responsive web sites?
