Ah, I have been doing the same this past month, except without the paying job part.
The books I've been using, and the order in which I've read them:
- Avinash Kaushik’s Web Analytics 2.0
- Andy Harris's HTML, XHTML, and CSS All-in-One Desk Reference for Dummies
- Sue Jenkins's Web Design All-in-One for Dummies
- Michael Fleischner’s SEO Made Simple
- Google Advertising Tools
- Designing for the Social Web by Joshua Porter
- Lynn Beighley's Drupal for Dummies
#1. You may not think you need this, but you do. You need to be able to measure outcomes, and you should be doing it from the get-go. Google Analytics is free and very easy to use, and the book is extremely well-written.
#2. Yeah, it's a Dummies book, but you're writing code by page 10. Another well-written book.
#3. Not a great book but it does give some ideas that #2 does not. You might want to go with a more advanced design book once you get this far, plus look online for free public domain themes under a creative commons license.
#4. This is for getting your site onto Google and getting good page rank. A very fast read.
#5. This enhances #4 (you can probably skip this one if you wish); it's more for if you want to go the paid search route.
#6. This one can also be skipped if you're not building a forums-type site.
#7. This one is skippable if you're not using Drupal.
Hope this helps. All are available on Amazon.
