Redesign A-Frame House Structural Drawings

Hello, Sadly I just paid someone else to do structural drawings on my A-Frame house and when I went to look at getting materials he designed custom brackets to connect the piers with the rafters. The custom made brackets are going to cost me over 15K to be made which I dont have in the budget...
