Where to find opportunities to practice z/OS CICS development?

Hi all. I've been assessing the feasibility of getting into COBOL/CICS development, since this market seems to be really active on my country and I'm also a bit sick of current trends on software development.

However, I'm having some trouble on finding an opportunity of getting access to a mainframe for practice.

Could anyone give me some ideas/directions? I totally consider paying for such access, naturally.

PS: suggestions/advice are welcome as well, as I'm still just thinking about taking this path. Besides, I think I'm well aware of what I'll eventually encounter in terms of code quality and maintainability -- I've been working with 'older' languages and legacy projects for some time now and I feel less unhappy this away.
