There are plenty of guys out there who know electricity. Theres even guys on here who will lend a hand. Figure it like this, most remodelers use subs, so you are paying into 3rds. subs/materials/company. Even if they dont use subs you are paying 50/50(material/labor). All of the work you are going to do is relatively easy. Electric I understand, I dont do much of it myself. So cut out the middleman and hire your own subs for things you dont feel comfortable doing. The more money you save in labor the better materials you can buy and/ have money in pocket. Let me know if you need any help with anything.
