Website Design

I need a website designed with the ability to take online payments. I had one designed already however I cannot get in touch with the designer to finalise it. It is an online competitions based company. The website I had designed originally is as follows:

https://halldesigns.co.uk/aghyarran

The one that I am trying to emulate in design is as follows:

https://www.rkingscompetitions.com/competitions

This is my rival. I need all the same functions as this website.

Thanks
