yes, really depends on the agent and how much effort he is putting into selling your property. But in most cases, since you decide to go cheap on agent fee and not paying the recommended 3% fee listed by the BOVAEA, it probably won't be in the agents first interest to market your property.

A good agent should be able to negotiate your property at a good price and never appoint an agent if they complain their asking price is too high! That's just very unprofessional and they should do their best to accomodate your requirements.

There's loads of phony agents/negotiators out there so make sure you check if he has a REN/REA tag and look up there REN/REA number to check if they're actually registered agents!
