1st get a proper domain for your business.(would be better if you buy a 3-4 year old domain) don't paste ads on your website. it will make a bad impression on the visitor,
avoid to sell hosting on forums.
Hey get a separate IP for your website.
628 website are hosted with this IP 18.104.22.168
i've a hosting business but have never mentioned the name on any forum. because it effects your business,
make a proper website, with ordering system, why would a customer call you, for a hosting.
1st give away accounts for free.
check your server, test your knowledge, what problems you can face, because there is nothing to do with free user
when you feel that, now you can handle a hosting business. then start selling.
Don't use the word "price". there are many other in market. who can kick you out in price matter. In hosting business, reliability is most important thing.
