Welcome to the forums!
He's so cute! You can house him with a furred pig just fine. Have a look at local guinea pig rescues or other shelters you should be able to find a pig up for adoption near you and you might even be able to set up play dates to see if they will get along. He will definitely need a same sex or neutered cage mate. Please don't buy one from a pet store if you can avoid it.
As for the cage, adequate space is essential for their health and happiness. You can scavenge for your own materials to build a C & C style cage for often the same cost or less as a store bought cage
(which are generally too small for pigs), alternatively you can buy one directly from the store at the top of the page if you don't feel up to hunting materials down. For cage size recommendations check out the main tab at the top of the page and remember that two male pigs usually need a bit more space so add an extra grid to the recommended size to ensure they get along. You can also build alternative cages using different materials, whichever option you find most convenient.
When you do get another pig make sure to introduce them properly or you can have a fight on your hands which can be more damaging to a skinny pig as they have no fur to protect themselves from scratches or bites. For tips on introductions read this website:

Finally, if you are tight on money I would suggest starting a saving fund for your pigs as soon as possible. Guinea pigs require a specially trained exotic vet if things go wrong
(normal cat & dog/small animal vets do not have the appropriate training) and exotic vets tend to be more expensive. I would suggest saving up to have around $1000 preferable over $1500 for medical emergencies unless you think you can soak up additional costs above the $1000 if need be
(it's uncommon that you'd have to pay that much but common enough that I'd recommend being prepared as much as you're able to). Also make sure you know where your nearest exotic vet is and an emergency exotic vet you can go to after hours, including their phone numbers. There's more information on all this in the medical guide linked above including how to find a good vet.
Anyway, I'm sorry for piling so much information on you! But it should give you all the basics you need for your pigs care and if you have additional questions you can use the forum search function or feel free to ask
. Skinny pigs do have some additional care considerations which you can probably find out more about by doing a forum search. Good luck and welcome on board!
