How many people get married in Nigeria annually?

I'm trying to establish a service business that would cater to intending couples. To validate my biz proposal, I need to tell how many weddings take place in Nigeria annually (estimate market size). You would not believe I have been to the Ikeja Local Govt Registry and their records are still entered by hand!!! Plus, to even see how many people got married in there in 2008, I need to get permission from some top-shot in Alausa! Is there anybody anywhere out there who can help with the desired info I can't believe we do not have a computerised databank of weddings, after all, such info is supposed to be at the disposal of the general public
