I don't show my load calculations on estimates.. You buy the job
you get to see about $300 worth of load calculations. This isn't a 
hobby. A good computerized Load calc costs upwards to a $thousand and up 
to $5 thousand with all of the duct, material, etc addons. Plus it takes 
a few hours to input and get it right. Inspection department has to OK 
it along with the work plan. I don't do the paper hob for my 
competitors. When they worked for me I taught them right and let them do 
their own work. If you want to pay for the load calc..That is business.. 
Free.. no way!
