When we bought this house the entire yard was fenced with either 6ft(back) or 4ft(front) chain link fence, except for a 16′ 2″ portion along my southern line. I have tried in vain to purchase 16ft of fence only as I did not need the 50ft section commonly sold at the Big Box stores. I saw a gentleman rehabbing a trailer park here in town, and hey, nothing tried nothing won. He sold me a 60 ft section for $25, about half of the 50ft section form the store. I did a lot of video watching, specifically https://www.youtube.com/user/fixafencellc who has some points for guys like us to DIY from.
Those were the two that helped the most, I hope they help you as well.
This one from Aldermenfarms also helped a bit with the idea of using the clamps to keep the fence from buckling over on itself.
