I've not used one.com but it looks like shared hosting. You could try and adapt this tutorial
One issue is you can't run your migrations without ssh access (although this package might help but it doubt it https://github.com/spatie/laravel-web-tinker) so you will manually need to setup and manage your tables.
I would look at laravel forge a $12 / month plus about another $10 for a basic digital ocean droplet (or other supported provider) but will save you countless hours on setup, configuration, deployment, etc
Theres a free trial if you want to try before you buy and an ace tutorial series here
Whatever you do make sure you dont expose anything outside the public folder to the web. E.g. if you have to go to /public/... in your url you can mostly likely just put /.env to get access to your secret configuration! Getting security wrong can be costly
