Audit Internship

Hi members, am an expat from Kenya teaching Economics & Entrepreneurship here in Rwanda at Riviera High School. I hold a B.Ed(Arts)degree in Economics & Business Studies from Kenyatta University, Kenya. I also hold CPA PART II (Section III) qualifications.
I have taught for the last three years and do feel that this is the right time for me to acquire practical accountancy and audit skill from an audit firm since am so passionate about figures.
I am a fast learner and as per now searching for an audit firm that would be willing to offer me an internship. I do not mind doing it for free since the major objective is to learn and acquire practical skills which are invaluable.
Please let me know of anyone there who would be of great assistance.
Thank you,
James Otta
