Getting Started....build vs buy

Good morning all... as you can see by the number of my postings I am very new here.
I am looking to build a tear drop based on the '47 Ken Skill Model 10 design.
But.. I have my first of many questions to get me started.
In your opinion...When it comes to the trailer chassis...build or buy?
I do have access to a complete fab shop, where I will build everything...including the chassis if need be, but in your experiences, is it more prudent to just purchase a new trailer chassis and skip that step, or is it more cost effective for me to build it?
Thank you in advance for any and all replies!
