Peoples perceptions are entirely different and people hear different things. There will be some people reading your pricing post and thinking it could get done for 1000 parts and 200 for labor (since 100 is not the right amount they will double it and think that should be reasonable) Then they will get many estimates until they find the guy to do it for 1200. For a time saving measure on the phone in your own local area, that would be fine, mainly because it will be you explaining that the distances, access, permits, electrician (in some places), pad leveling, tree removal and materials is significantly higher than 1200.00
