The laws and procedures vary depending on your location, but in many jurisdictions the laws are very favorable towards both labor and material suppliers and can be costly to untangle.

Does anyone have recommendations on Kitchen cabinet suppliers?

Stick to your guns, learn from your mistakes and build a trusted network of suppliers.

Pay for the material directly to the supplier, never to the contractor.

Ideally the "base" plans would have had houses built from them, and even better - if someone has personal experience using plans from that site.Additionally, I'd want the plans would have a take-off/bill of materials list with them, to get an idea of cost, since most of my materials I have specific suppliers that are quite a bit cheaper than "average".The issue is exactly as you mention: I'm worried that many of the websites selling "house plans" may be of questionable "quality", so I'm hoping for some personal experience on using plans from specific sites.

Cabinet suppliers are raising prices to bring excessive lead times down.

This is how we found the largest commercial supplier of flooring in our area who gets the best product for better pricing as their volume is higher.  

I have a local supplier that gets me 1 in thick granite slabs, mostly black in color.

so money at close 400 a month. just need 1k and good credit per house.So lead comes in and the major supplier in our chain had a radio show and was the take out lender..

However, after reading about what a business you have selling rights to developers, I would assume that on the other end of your business, the demand for rights is very high and therefore the supply is low (you profit because you are a supplier).
