How goes the battle Cholo? As far as the flooring people do it both ways. Personally I think it's best to bump the flooring up to the base cabinets, because if you have flooring problems later on, you don't have to take up the bases. I'm not sure how many stores you have to pick from that sells cabinets but I'd get at least two kitchen designers out to look it over and design things for you. Use quality cabinets, have enough drawers, those are important but get left out so the kitchen appears less expensive. Get self closing hinges. Decide if you want an island. Decide what you want for counter tops. Ask both designers if they have an installer, it only takes one even for a good size kitchen. Typically if you use granite or some stone they will cut everything at the shop and deliver and install it with their own people. The only other thing you need is a tile guy for the back splash, and a flooring guy to redo the flooring. Typically everyone that sells the stuff also has installers. Ask for how long it's going to take to install, typically a day, sometimes two. I typically am my own general and schedule the subs and let them know what I expect from them in terms of when they can get in and when they need to be done. (Be realistic) The bathroom I had redone, the tile guy was in the middle of his job and I said I expect this to be done by tomorrow. He said how late can I work. I said, I don't care how late you work, I expect it to be done tomorrow. .
You can do your own demo or hire someone. Try to not tear out the drywall, and do any touch up necessary to prep things for the cabinets and the tile. Also before you schedule anything find out when everything is going to be in and delivered. May take longer than you realize. The designers should be able to give you a list of what you need to pick up or at least consider in terms of a sink, faucets, handles, etc. Good luck.
