Big or small Real Estate companies to sell property with?-Niagara

[Stanley Li]

We have a fairly new property (4 bedroom 4 washroom, not including basement, <3 years old, all sides brick-walled detached home) in Niagara Falls, Ontario, 1 min drive from QEW high way, and are considering selling to put everything into a much better home for ourselves in North GTA, where we live. We've had pretty terrible experience ourselves when it comes to agents, so we are a bit put off doing this. 

In terms of the speed (date on market) and all-inclusive services (cleaning + staging + selling), should we be looking at big companies like ReMax or Royal Lepage? Or other smaller options when it comes to the Niagara Region? Our reasoning is that perhaps the bigger companies would have better network for selling. Any suggestions or tips would be great!
