I need an automated sales funnel build for an IT company

I need an automated sales funnel build for an IT company;

1. We receive website enquiries that come to our normal business email account
2. We then manually respond to the clients -> (no templates for this)
3. We manually setup virtual meetings ->
4. Then manually create quotes -> (no templates for this)
5. Manual Follow Ups (no templates for this)
6. Don't have a central lead database

We need a setup that will automate all this and make life easy in our business.

Respond only if you are very sure you will help.
