I apologize if this has already been posted (Im sure it did ), but with my poor english using the search tool I cant understand if I found what I need.

Im starting with a friend an online service.
The user enters in the webpage, full a few information, and after acepting terms and conditions, it should appear an automatic address (that if it has the amount of payment, would be better )

I dont know how to put that in the webpage. Does blockchain has this kind of service?

Also I would like after this, to check if the payment has been done correctly, so I can provide my service to the user.

Sorry if this post has already been made. I would apreciate links to those posts. I installed apache2 and mysql with php a few weeks ago Im still learning, but working in bitcoin community its a dream I want to acomplish (:

Thanks all for your time.
