GC Taking a long time to get an estimate

[Heath Thomas Jr]

hey all, I am working with a few different general contractors and trying to get bids. I just had a quick question..why is it that getting contractors to send bids is such a long process? (Besides the fact I'm probably talking with some unqualified contractor)

I was able to to the estimation myself and get the same numbers as they did the same day. But it's taking one of my contractors almost 2 weeks to return an estimate! 

From a GC perspective why does it take this long? Anyone else have these issues? Is this a huge red flag when finding a GC? 

Other than the long timeline for the est. I have known and trusted this GC for a little while..but maybe the project is over their head..
