I myself am currently looking to build some in my market so I am talking to suppliers currently but that is what I have found on average.

Sometimes they get new, factory-blemished items, scratch and dent appliances or "oops" paint.Alibaba.com or any Chinese supplier can provide inexpensive flat-pack (ready-to-assemble) cabinets for good prices, but you will wait weeks or months to get the products and if one thing is damaged or incorrect, you will wait weeks or months again.

I have a supplier for the materials, a person from one of the big companies in that field.

For example: an HVAC installer could charge you as much as $2,000 for a furnace that you could buy directly from the supplier for $500.You need to apprise yourself of the true costs of what you're trying to do, so that you can plan most appropriately for your expenses.

It probably wont make much of a difference but it cant hurt either.In the future you can try doing these two things1) When contractors go to home depot or any of our suppliers to order material on our account, the suppliers are not allowed to moved forward without calling our office and getting authorization for the order.  

Competition is brutal for the suppliers so they're forced to keep their margins razor thin leaving little wiggle room for generosity. 

I don't know of any pattern block.Your best bet is to hit the internet and search for images of what your like and then drill down to local suppliers. 

You can obviously search Google, but a method I've used before in addition to my network is to visit construction suppliers (companies like ORCO Block) who supply builders with construction materials.

We all have contractors and suppliers, and our costs are not the same. 

It can help… Shop cabinets suppliers for 20-30% discounts, call wholesalers for LVP flooring, countertops, appliances, etc.
