I would like to build something that looks sort of like these houses

I have rented a second 20 foot container and have been scouring the free section on Craigslist for everything I need to put this house together and storing it there until needed. I am on a roll!!! So far I have aquired;
-a complete matching bathroom consisting of a jacuzzi soaker tub, toilet and two sinks with all the hardware, a steam shower unit, another toilet, the propane cookstove, a stacking washer/dryer, an under-counter dishwasher, four old-fashioned heavy- as -shit, water radiators, 20 french style wood frame windows, 4 interior doors,all my salvaged light fixtures from the boat and apartment, and about 60 bags of insulation.
Not bad for only three weeks into this. So far I have spent in total for all of the above $2,440.00 Most of that was $800 for the floats and $1,100 for the steam shower ( original cost over 3,500.00, I got it new in the box for a third of that, so great deal as far as I'm concerned).It's a shower/steam room and has jacuzzi jets to massage your back! I can't wait to try it out.

So as it stands now, I need plywood and 2x4's, vapour barrier, black tar paper, cedar shakes for siding and roofing,drywall, some kitchen cabinets, a fridge, two bathroom cabinets, two exterior doors, a wood cookstove, a propane water tank and an electrical box and wire along with some plumbing. Some of this stuff I can get for free, the rest is affordable.
I'm thinking I can build this house for under $10,000. That's my goal anyway, it will be interesting to see if I can pull it off. Finding the insulation for free today was a super bonus. There was an ad for 60 sheets of free plywood the other day. Haven't heard back from the guy, so it might be gone already but that would have been enough to build my cabin for sure. Im still keeping my fingers crossed that it comes through.
Now that we have moved into Davids floathome full time, he has been putting tons of hours into fixing the place up. Things are coming along nicely. He hooked up the jacuzzi tub I got last year and a new stacking washer/dryer. The bathroom sink got plumbed in and the tool room super organized. The loft bedroom is now a reality. It still needs some insulation, the hardwood floor nailed down and a window installed for ventilation but its a wonderful space already with an awesome view out the main windows in the living room. We found a free hot tub on craigslist and finally got it running out on the deck. Its so awesome to sit out there after a hard days work and enjoy the sunset from the tub.
