Not sure if they are still active but some people offer very affordable corp member limit maximization service. I myself used such service when creating my corp and it went without issue. Make sure not to have any corporate property when you grant access to the service provider just in case.
Edit: He seems still being active…
Costs 5 mil ISK so pocket change even for a new player.
Edit2: Oh it seems he stopped posting since Oct. 27. last year so not sure if he is still active but worth dropping him an EVEmail. If not others might be providing similar services.
