A good way to help reduce barrel weight while keeping the thicker profiling is to have your barrel Dimpled. Dimpling will also give you more surface area to help with cooling. This pattern has offset rows of Dimples to help keep them as tight as possible while still keeping enough material to allow it to stay rigid.
Pricing is based on the length of the barrel primarily. Longer length barrels require 2 setups which takes significantly longer to do. 16.5 is the longest I can do in one pass. Any longer requires a second setup.
