Need Information About Importing Laptops Into Nigeria. (no Partners/agents)

  Hi I need to know the procedure involved in importing a good number of laptops (from Dubai). I own a computer shop and would like to bring my laptops straight from there as I have been residing there for close to two years.

I simply need to know the procedure at the Nigerian airport when I bring the laptops in, what are the custom duties if any, what do I have to do to get the laptops through the airport (MMIA) without any hitches whatsoever.

Hope I was clear enough. Thanks in advance.
