Before you ask me for a (How much is it going to cost me price) you first have to define the level of performance you seek.
Performance comes in stages and each stage brings with it additional time and additional costs.
Answer the questions: What do you want. What do you need. What is your budget.

My primary business is building Hot Work Chainsaws. Hot Work Chainsaws are saws that cut timber all day.
These saws require minimum weight and maximum power. That is what I build.
That is what I deliver: reliable, Dyno Proven powerful chainsaws.

I also repair chainsaws to get them working good as new keeping them original.
