dude..why not buy a grappling dummy? If you cannot find a partner, I think a grappling dummy would suffice and maybe when you'll have your chance to wrestle with a real human you would be quicker and more prepared. I'm just saying, but it's up to you if you wanna have one. You could also pay a BJJ practitioner to be your dummy, an hourly rate would cost about 10 bucks or less. Don't wait for things to happen, make things happen.
