Your question half, whether you want to make or renovate your own kitchen or you want to make other’s kitchen.
In first scenario if you want to make kitchen for your self then contact Kitchen designing companies or interior designers of your area. If you will go with carpenter then they won’t make modular kitchen. They only make plywood kitchen that’s all. As there will be no modules, no finishing, no ergonomics. But if you will go along with good modular kitchen companies then they will provide you the modular kitchen. But certainly it will be costlier than a carpenter.
In second scenario, if you want to make a modular kitchen for client’s then you need to learn it from any Interior Designing Institute or WoodGood
At WoodGood you will learn from scratch to advanced level about modular kitchen.
