Filling the site with Joomla

There is a site on Joomla, you need to do a paid consultation, the scheme is something like this: the visitor fills in the form on the site (your name, e-mail, phone, your question), after which he is offered to pay for the consultation in different ways (webmoney, Ya.money, SMS, bank card, etc.), after payment, I receive a visitor's question with a confirmation of payment.
