I don't know where you live, but in the "developed" parts of the world this is illegal. There will either be some government agency or some council of credential-giving institutions and they will give you a license to issue degrees, or most likely they will not give it to you.
In the US, you can just make up degrees — but you have to be honest that you’re unaccredited.
Accreditation is regulated by NGOs who need government approval and without that you cant received financial aid (or participate in some programs) — but you can hand out pieces of paper for completing your program.
