Leadpages Domain Setup

I have a project that I need some help with;

We have started using leadpages.net and we are wanting to host our lead pages from our own domain www.soundtesting-uk.co.uk rather than the .leadpages.net domain. Are you able to set this up for me?

I have been trying to do this over the last day or so but have not managed to get the domain to connect. I can give you access to Lead Pages, as well as to where our domain is registered (Freeola). I have been sent useful links from Lead Pages Technical support (https://freeola.com/support/domain-dns-setting.html) and (https://support.leadpages.net/hc/en-us/articles/218820517-Set-Up-a-Custom-Domain) .

Can you help?

Thanks
