I was hoping for some advice on how to finalize a contract I am completing with a contractor/construction company for a flooring project. Unfortunately due to a number of reasons I was unable to make this a DIY project and have turned to a professional!! Being my first major project I’m not very knowledgeable at negotiation/planning, and looking for tips: 1) What percentage of the total cost should I be putting down? Total project cost will be about 6500-7500 depending on a few variables - I estimate 2500-3500 of that will be materials (see #2). Contractor is reputable and has done work for two friends of mine without problem; but I am still uncomfortable providing too much cash upfront. 2) I was quoted with a fixed price for labor and material on this project (removal/hallaway, leveling/subfloor, install of new hardwood). I am looking for ways to cut costs by possibly obtaining some material at discount, but the contractor is reluctant to breakout the actual cost of the hardwood, and claims I'm not going to be able to get cheaper then he provides. This sound abnormal, and any advice on best way to handle? We are meeting face to face later in the week to finalize and writeup contract. Thanks all, posting and browsing forums have been a lot of help!

I am looking to refinish my oak hardwood floors and the guy at Home Depot is saying I should rent their oscillating sander and not the drum sander as it is easier and safer. But will the oscillating sander work? It would definitely be preferred if it is as easy as the guy says, but will it work and what would get the best results?
