I’m a small employer and I’m unable to buy main domain because it’s expensive for me
So I need of a sub domain provider that gives good packages to create own website. If you have any information please let me know.
Any recommendation will be highly appreciated. Thanks!

You can only use a subdomain if you own the main domain - your best bet is to choose another alternative top level domain (e.g. .net, .biz) and use that instead.

Not sure what type of site you want, but you can register with wordpress or blogger and create your own blog over there for free.

Yes! I would prefer < removed > that provides sub domain for creating our own website. You can create a complete website for only $1. There are so many packages that you can choose according to your requirement. It’s really very economical and reliable. Hope this will help you.
Good luck!
