I can't recommend the Coursera compilers course highly enough. It was enough to get me from zero to a fully working compiler. Albeit for a simplified language, and a really bad compiler :-) If you did it in one of the languages for which scaffolding already exists, it'll be even easier (I did it in a different language, so had to build everything from scratch).
