Redirect two domain names to a website

I set up a Design company. I have recently changed the name of the company and have purchased two domain names xxxxxxxxxxxxxxxx.co.uk and xxxxxxxxxxxxx.com. The domain names have been purchased from two separate web hosting companies. I would like a Web Consultant to direct the two domain names to my website. I understand that I will need to purchase the hosting for both the domain names before redirecting the domain names to my website.
It’s a simply job, but I need a web technical person to help me.
If you have done this kind of thing before and have the technical know how I would like to hear from you.
