Working In Nigeria.

Hello,
Ive visted Nigeria for the past 3 years on holiday. I have worked in IT in the UK for the past 7 years now but now specialise in Application design and support. My educational background includes a Business Degree and a Masters in Computing. I am now considering going to work in Nigeria for say around 18 months to experience the country of my heritage. I've been told to try oil companies and telecoms too. I would probably be interested in working in Lagos in particular. 
What is the potential salary i could earn, and does anyone think i might enjoy it, or at least survive. What is the working culture like compared to the UK. Are there any Nairalanders from the UK, who have been to work in Nigeria. Let me know.Thanks.
