How to organize open WiFi and advertising of the organization on the landing page?

Question

network hardware

Task: to organize open WiFi for clients on the territory of the organization, so that the website of our organization opens upon the first connection. How to do it?
The budget is very limited, so I would like to take, for example, some inexpensive D-Link router and set it up accordingly. But the standard firmware D-Link DIR-320 rev.B2 (what is at hand) does not allow this.
How to do it?

Answer 1

if D-link, then you need to get confused with OpenWrt.
or look at Mikrotik.
You need to set up hotspot.
