Southall has launched a website called asknevillesouthall.com where he says: "you can get personal advice from me on any football related subject. Simply pay for an email or phone consultation below, and I will be in touch asap."
Southall will respond to an email within 72 hours for a fee of £49 while you can conduct a one-hour conversation with him over the phone for £99.
The Welsh stopper is considered one of the greatest British goalkeepers of all time and was named Football Writers' Player of the Year in 1985 – the last goalkeeper to receive the honour.
Southall played a club record 750 times for Everton between 1981 and 1998 and was capped 92 times by Wales.
Southall explains on the website: "Surprise, after many years of people telling me to get online, I have now dived in and got a website set up, mainly so people can ask me questions as everywhere I go goalkeepers come up and ask me for tips and advice, and well I can’t be everywhere all the time.
"So hence the site and the option to either arrange an answer to your questions by email or a one hour phone call chat."
