I was in the same position about 6 months ago and I found quote roller. What I like most is their support but also their ability to add new features. I tried Bidsketch, but was not impressed by their lack of "wanting to upgrade". I tried quoterobot as well and its was ok. There's a bunch out there and most have a free trial, but best one ive seen so far was quote roller. We started out with 1 account and now are up to 10 users, so it's good for small and large shops. The only thing that's missing is a custom domain of which i need. I hear its in the pipeline so we'll see!
