Garden Frame (Sandy)

I am looking for a frame to cover in netting to protect my Blueberries (quite tall bushes maybe 6 foot) I dont want to buy/build anything yet as the garden is a mess and not being done properly until the house is finished. I wondered if someone might have a lean to greenhouse that the glass is broken on or a childs monkey bars that are no longer used? that i could repurpose ? Thank you :)
