Help with providing a quote to client

Hi Softr Community,

I am currently looking into build a professional website for 2 clients.
One is simple website with not much custom code and features. Other one requires custom code and other advanced features such as membership, user groups and permissions, gated content etc.

I need help with providing a client with details quote. I am just wondering if you can provide template / example of quotes or any other resource that can help me with preparing a detail quote for a client.

Thank you.
