I need a professional looking website for a training company.

We are a small training company and need help with a website.

We already have a wordpress subsctiption and Elementor Pro but dont have the tech know how to make it into what we want. The site will need to have a landing page and some pages where we can list the training dates and course information. In addition, the site will need to have a checkout in place and will need to be able to take payments.

There is already a site which I have worked on as a template but I cannot go further. There will need to be some optimisation.

An example of the website would need to be like the following https://www.dulsontraining.co.uk/ and https://www.mdrtraininguk.com/
