The problem of vpn is you need i fix ip address that mean you need to pay for the fix ip

Not so. Some types of VPN need a fixed public IP but certainly not all. But in any case, it is generally best to avoid a VPN unless you really know what you are doing. Much better to use a service such as CloudFlare Zero Trust.
