Looking for a Freelance English teacher in Lagos

Hello, My name is Ernesto and I am the head of Corporate Language Training of one of the largest language training companies in the UK. We have had a request from one of our major global clients to provide English lessons to a member of staff relocating to Lagos. It has proven to be quite a difficult task to find a school which can provide freelance teachers. I was wondering if anyone could help with any information regarding a school or freelance teacher that could provide us with such service. Maybe there are some expats with teaching qualifications and experience who would be interested in this opportunity. The total number of hours for the course would be 100. I look forward to hearing from someone. Thanks in advance. Kind regards, Ernesto Forner
