I need minor changes to a Worpress site

I have some downloads (information products) on my website at www.silverliningep.co.uk which have stopped downloading. They are / were linked to ActiveCampaign. I need them to be reactivated and a new one added.
I also have some smaller downloads which I call factsheets which I would like to add to the website - maybe on their own page, and maybe on a page that the three larger downloads can be on as well. These will also need to be linked to my Active Campaign CRM.
This may lead to a rebuild of the website later on and you will obviously be well placed.
