These days ISTQB Foundation seems to be the minimal course that everyone has listed on a job description.
There are plenty of places to get them done. I got mine at Plantit who i really recommend. Its a 3 day course and they are a lot more hands on with their approach. The course was well facilitated and i found the material to be more extensive. They also do a guaranteed pass for the Foundation certification and a refund in the rare instance of failure.
