i just setup perforce for my team, followed this tutorial, in this tut, they use vultr, you get 125GB hdd space, 1000gb bandwidth for $5 per 28 day month, billed per hour that your server is active. for me that’s an awesome deal.
i’v had trouble using their “consol” on the page to manage the server (space bar didn’t work) but you can use putty to log in real easy
as a bonus, they do promo codes for referrals, you get a free $20 credit for the person that uses your code, and a $30 credit for yourself if they are active for more than 30 days and spend $10 (shameless referal link 
)
:Edit: perforce is free to use for up to 20 people
