Set up wordpress and tell you how to use it

I started a website on WordPress, I need basic configuration: anispam, protection, SEO, setting up the texts of letters, alerts and a story about how to do it yourself.

List:
— configure emails password recovery, user registration
— setting up system messages and in the form of login and password recovery
— add some standard set of plugins to improve SEO
— talk about good safety practices
– tell how and through whom it is better to accept payments (how it is issued, what you need to have, which provider to choose and why).

Result of the work:
- Customized emails and messages
— plugins are installed, instructions on how to use them are left
– a consultation was held for 30-60 minutes on how to use the site and connect online payments.

Setting up as much as possible without hardcode in functions.php so that I can change everything through the interface. In the response, please write approximately how long it will take and how much it will cost. Without the price and timing, I will not consider the response :)

P.S. The price in the project is indicated to pass the validation of the form. Please write your suggestions.
