Write a selling text for the site

You need to write an effective selling text for the site
The text should be addressed to a specific client.
Our goal is to get the customer to contact us.
The text on the site should serve as a good sales manager:
Answer all questions of the visitor
Focus on the strengths of the product (service)
Argue the benefits that the client receives from working with you
Encourage and encourage you to do the action you need to do.
Exordium (introductory). Start with an intriguing statement that will grab the attention of your target audience.
Narratio (exposition). Give readers a problem that your product can solve.
Confirmatio (approval). Promise a solution by backing up the promise with compelling evidence.
Peroratio (conclusion). Name the benefits that the person who took advantage of your offer will receive and call for action.
Attention – Interest – Desire – Action – Attention – Interest – Desire – Action
Problem + Promise + Arguments + Solution = Persuasion
