Improvement of our google ads marketing

Hello
Currently, i am doing google ads marketing myself. Overall it is okay. But I want someone to look at my website to see if there are any things to improve. My website is www.nuovocoros.sg. We are specialized in serving customers with countertops and dining tables, and feature wall and island top installation of sintered stone material.
I want homeowners who will do the renovation of their homes in the near future or interior designers
who will serve the homeowners for house kitchen top renovation in Singapore, not other countries.

I want to run the google ads with manual PC and match exact keywords so that i want really needy people visit our website. I do not want the people who will not become our customers visits our website because it made me spend the budget only.

Also I want to remove two campaigns that have been created by me some months ago.

So i am looking for the specialist for google ads who has a lot of experience.

Maybe you can check my website and discuss with me how to improve the clicks by the potential clients in singapore before changing them.

Waiting for your reply.

Thank you
