12 yrs COBOL on DOS/NOVELL, no mainframe experience

Located in Raleigh NC, working full time (PHP/Perl MySql, etc.) I could only do part time Cobol work if somebody needs it.

I have 12 years of Microfocus COBOL experience. Managed 2 million lines of COBOL code all by myself for 6 years (ended Cobol work in 2006, have been in PHP, Perl, C#, MySql ever since).

What training resources are available in the Raleigh, NC area to get the Cobol skills brushed up and get me mainframe experience for the first time? How could I get the mainframe experience that I am lacking?

Thanks for any answers
