Want to put my CRM out there, how should i host it?

Hello I've developed a small, CRM system that i would like put out there for people to use, but have to admit i am a bit lost on how to host it, as it needs a unique URL.

so I'm thinking of doing it self hosting and open source like Wordpress, that would require some sort of wizard on start, that would add the database info to the environment file from users input? put there are still a few things that would need to get uploaded to the database before it actully works, how would i go about this?

Second option could be that you sign up get a url companyname.crmname.com, and then it would register everything automatically, but how would i got about generating subdomains automatically from a users input in a signup form? Also again i need it to upload some data to the database on signup, or some sort. Hope someone can point me in the correct direction, as i would like to learn how to handle this.

The CRM is coded in Laravel 5.2
