Cardiff Blues chief executive Richard Holland says 25 applicants have applied for the head coach role that will be vacant at season end.
According to the BBC, the chief executive said that on Monday a meeting will be held with Cardiff Athletic Club to discuss possible Arms Park redevelopment and also said the region would not hand control to the Welsh Rugby Union.
The Blues want to stay at the ground while any building work was ongoing rather than leaving for another city centre site. They also indicated new sources of revenue could come from ground naming rights, television deals and sponsorship.
Former Wales captain Gwyn Jones critisized chairman Peter Thomas after Wilson announced he would be leaving.
Holland said contenders include former international coaches and that a shortlist would be drawn up soon.
The successful candidate will most likely officially begin his tenure at the start of next season.
Holland added that the working relationship with Wilson is strong and will continue until the end of the season.
The chief executive also said high-profile signings of foreign players will end and focus will be shifted to developing homegrown talent.
Holland added that coaching will receive loads of funding but funds are still available to bring players in if required.
Holland says they will aim to hold onto Wales lock Seb Davies, while Wales flanker Josh Turnbull, full-back Rhun Williams, Josh Turnbull and prop Corey Domachowski have agreed to contract extensions.
