You could also do work for yourself on the side to learn the tools. I've had several candidates for an open position tell me they are interested in BI, but they haven't done anything with the tools. I broke into programming and database work by doing things on my own time to learn how the tools work. I started data warehousing as a work requirement, but I'd expect someone who told me they wanted to break in what they have been doing on their own and why they find it so intereting.
