I have different pricing plans for different needs.

Right now I cap my time and materials rate at $120.00/hr for local emergency/urgent projects without negotiated contracts. This price is subject to change as market conditions dictate.

I can provide lower rates for work that is not urgent or time sensitive, especially for local home owners working on their own residence. Contact me to inquire.
