I doubt you will be able to get a forum member to give you a number you are looking for. Prices vary widely between downtown Toronto and Kenora. Do you homework on finding at least two well-recommended contractors and consider the estimate cost of the one(s) you don't go with as the cost of good due diligence. Any estimate should include the permit costs. Wiring rules for finished basement spaces, bathrooms, etc. are pretty much the same as upstairs. With open walls and ceilings and no panel work the cost should be fairly reasonable.
Although beyond your question, remember your need for a permit for the build, plumbing, egress windows for the bedrooms, etc.
