Move my WIX website to my own .com domain

I currently have a WIX website (https://championtraining81.wixsite.com/website) and have just bought my .com domain. I want to transfer my wix account onto my new domain so that I am searchable on google. I need to be searchable as I am a personal trainer and trying to grow my business

So what I need help with is for someone to point my new website domain to my wix server address.

I'd like a website that will it be easy for for me to manage and update. For example update to my services, new video content and photos. Ideally I'd like to have some online videos which clients could access for a fee. Also I'd like it to be user friendly, so that clients can easily see the service they are after and pay upfront. Also an interactive calendar so that they can book timeslots.

I'm not sure if this is doable but I'd like a function where I can do online classes via my website. So say for example I have a class at 2pm and 8pm the client will be able to log onto the website and participate. This is a nice to have as I can probably do this via zoom.

I've already had quotes for this to be done, which are reasonable, but want to ensure I have the right person for the job.

All offers are welcome
