…I do not need a year or years of support that pfsense offers, i need a one time setup and access to future support if needed...
Isn't "access to future support if needed" exactly what a commercial offering does?
Anyway, as others have mentioned already, maybe post your basic network layout and things you need to get done so we have an idea of what you are talking about. Right now it can be anything from a single WAN/single LAN home setup to a perimeter firewall for a Fortune500 company. ;)
