If you'd like, I have a complete chain tool that you can borrow. The tool has the capability to break the chain, press on the side plate of a new chain's master link, and to "rivet" the master link pins. Using a rivet-type master link is the strongest alternative to using an endless chain, and doesn't require swing-arm removal, and only took about half an hour or so to put the finishing touches on the chain. But to add on to what Moe is saying, installing your new chain and sprockets yourself is not at all that difficult.
