Does anyone know how to send a quote email template to a new lead with information that they selected from my site?

I have the API connected and I can insert a new lead, I just cant figure out how to send a quote email with html content in it displaying the price of what they selected and the packages they chose. It will also give them an option to accept the quote and schedule a time to have the service completed. 

Someone PLEASEEEEE HELP!

Thank you!
