There is no requirement to get a hosting package, if you only want to get a domain name. You can easily register your desired domain name with some popular registrar like ZNetlive https://www.znetlive.com/
, GoDaddy or BigRock.
After getting a domain, you just need to set the DNS records, to redirect it to another domain, from the control panel you get from your registrar.
All the three registrars mentioned above are very reliable and offers dedicated support in case you need help with managing your domain.
