I don't believe there is any such thing as a "standard" solictors' consultation fee. IME a well-known, established, specialist practice with a good reputation can pretty much write their own ticket, whereas a new practice might be more open to a negotiated fee.
As ClubMan suggested above, maybe lift the phone and ring around, otherwise you may be in danger of being like the shopper who whinges about the price of spuds in Dunnes, but never checks Tesco, SuperValu, ALDI, etc.
