I'd personally find a cheap switch with fiber ports on both ends and use fiber. It's non-conductive so a lot of the complexity of grounding and lightning protection is off the table.
may cost a few hundred, but if you fry you're pc in the shed from a lightning strike it will probably cost more than that.
2.5gb unmanaged switches with 10gb sfp ports can be found for $50-75ish new and sfp's are maybe 10 a piece. Depending on the local market you may be able to find a used Cisco 3750 for $10-20. If you just need one port you can find a pair of 1gb media converters with sfp's for about $60. You can find pre-terminated direct burial fiber in various lengths for $110 or so for 250 ft, if you want to go overhead run a steel wire and attach the fiber to it, but you probably still want the armored fiber.
Depending on the speed and line of sight, a wireless point to point bridge may be an option.. you can find a pair for anywhere from $50 for 300mbps (I wouldn't bet that's real world, probably 50-100mbps) to much more expensive options (I ran 4 between 2 buildings at my last office that ran at very high, licensed frequencies that were probably $5k a piece, but they did 10gbps on a good day, and we're pretty rock solid even in the rain)
