You can get a renewal based on signing off five students with the previous 24 months with at least an 80% pass rate... sounds like you qualify for that. I'd call the FSDO and ask them what paperwork they need and make an appointment well BEFORE the expiration date, just in case there are any snags. If you miss the expiration date for any reason, there will be no waivers or any way to renew without a checkride.
You can also do a FIRC, which is 16 hours. Various schools (including AF) do these over two days, typically on weekends. There are also online FIRCs, most airline people knock these out in hotel rooms. The AF program is nice because you only pay for the first one and then you can do them for free forever.
If doing a FIRC, make sure you understand how the paperwork will be filed... you can usually pay the school extra to do that but make sure you know what paperwork you have to submit and when you have to do it. AOPA/Jeppesen requires you to get the documents notarized, but naturally they don't tell you that when you sign up for the course... you only find out at the end when you try to submit the docs. The one and only time I did the Jepp FIRC online, I was scrambling to find a notary at 1800 on the last day of the month
