Building Plans

I need building plans for the following building. 18.5 ft x 60ft ft building. Side walls will have a "H" metal beam running down the lengths of 60ft, with metal support posts (not sure how many support posts are needed) Side wall will not be needing anything on the face because of already existing community side walls. Flat root with trim-able joists running across the 18.5ft every 16inches. Front wall completely open because I am using existing facade. Back wall needs one entry door and a 10x12ft high garage door. Property will be on a concrete slab. address is 111 w main st. Brook, Indiana 47922 to get a visual on front facade.
