The countertop people came to measure and do the countertop/island templates last week, so (fingers crossed) the countertops should be in this week, and then the Plumber and Electrician can complete the hook-ups to the appliances. Once that's done, we'll have a working kitchen, possibly by the Memorial Day weekend!
I am not going to update the project plan again, since the remainder of the work after this week will be tile and paint, and since we've stretched the budget to the max, we will likely take the DIY approach to these tasks.
I did get a comment from Steve who led me to Anchor Bay Tile, where I ordered some samples. From what I saw on their website, I think I will be able to find the tile I want within budget! Which goes to show, never rush a decision. Mom, to clarify, that statement does not mean take 25+ years to select tile, just take a few weeks.
I have had to place additional orders for cabinet hardware, which I'm sure means I've spent more than planned on shipping costs, but the lesson here is to carefully count the number of knobs/latches/pulls and have someone else confirm it!
