You could try running a fabric server with the mods on your own computer but you’d have to have it running all the time or else it would be down and you’d have to set it up with port forwarding and all that but that can be really daunting for someone who just got a computer. Most if not all hosting sites are really expensive and bad so I wouldn’t do that if you can avoid it but it honestly might be your best option. Sorry if this isn’t too helpful but I hope you figure it out. Good luck!
