Set up DNS to correctly point domain to web server

Hello,

Thanks for acknowledging my job post.

I am doing work for a client and I need some help.
I am trying to point a new domain registered via name.com to a web server hosted on DigitalOcean.com

In this case, I want front-end users to be able to access my website via
http://www.domain.com
www, domain.com
domain.com

Could you please help me correctly update my DNS/NS records to make this happen?

This is a very simple task so I am offering no more than $15..

Greatly looking forward to your proposals for a quick hire!
