create property damage template in excel like xactimate software

I am a roofer and the standard software for estimating property damage is called xactimate software you may google it online if you want. It is very expensive so I want to create a template I can use instead of that for now. Please see this page my friend gave me who is also in roofing business and create it in excel so all the patterns configure the same. Create the same fields and names of items. For example, at the top it reads "waste@" and he entered 15% which then multiplies 15% times 27 which ends up equalling 31.05. Add the misc at bottom just like it is so I may add my own fields. And BASE SERVICE CHARGES just like it is so that all columns add up at bottom right as they should. Overhead and Profit is the same as O and P. Please add my logo also to the header.
