I've had zero luck find an engineer or architect for small residential work, and don't think I'm alone. It's very unfortunate.
The problem is that most of the people that request these types of jobs freak out when they get an estimate on the engineering cost, and walk away. After a few of those, you'd also ignore small possible jobs if you have plenty of other work. It's like how most body shops don't want to quote to paint a hood on an old car as long as they have plenty of insurance work.
I am not a civil engineer, I'm mechanical, but I worked for a contract engineering firm and have seen the above sooo many times. We'd have individuals come in for a quote on a patent drawing, and when my boss would give them an estimate, they'd freak out over the labor rate and cost. He'd tell them it was a cheaper labor rate than the local Ford dealer, but it didn't matter to them. After a while we even turned down quoting jobs from one large local company because after wasting hundreds of hours quoting large complex projects over a few years, we never once got a job from them.
edit- I agree with the above post- call a truss company as they would have to have a licensed CE if they do custom trusses. Or use someone on contract and could refer you.
