Being married to an electricion, I can tell you that you can have your local power company bring you another line in from the pole unless you can loop off of your existing panel. Then you can install a 200 amp panel which will give you safely three 220 plugs and several 110 which the stoves will run on. Panel, wire, outlets, wirenuts will probly run you $230.00 give or take depending on how much wire you use (12/2 romex)and where you purchse the items. Then add probly a day or two of a pro to install at anywhere from $25.00 an hour to $75.00 an hour depending on your local rates.
