You may just apply for a China F business visa from the China Embassy or Consuate in your resident place in Nigeria. No appointment is necessary for visa application, and you may just go to submit the application in person or entrust a friend or travel/visa agency.
The required documents include, your current passport with at least 6 months of validity and at least one blank visa page, completed and signed Visa Application Form with one additional passport photo, invitation letter of a duly authorized Chinese unit or confirmation letter from a Chinese government office and round-way air tickets.
A usual visa application process takes 4 working days, but you are under urgent, so you may request expedited 2- 3 day process through paying additonal fee.
