The best way to get hold of the imaam is to come to the masjid and go right up to him (at an appropriate time of course). Alhamdulillaah there's no need to set up an appointment with a secretary like you see in some other masaajid. The imaam is not such an exclusive figure or celebrity.
As salamu alaikum. Akhi it would be better for to go and speak to the brothers directly. Inshaa Allah.
