Rollers (Ashfield CA14)

I need to move my shed about 8 feet. Has anyone got anything that I can use as rollers? Or to slide it. It is 6ft x 8ft wooden. Will obviously be empty. Scaffold poles and round fence posts have both been suggestions but if you have any better idea I would love to know. I hope to move it before Christmas so a new concrete base can be laid. Once the concrete is set I will need to roll it back again. After that the rollers won't be needed so I can offer forward or back on Freegle. Hope someone has a good suggestion, better still the tools for the job, for me. Thank you.
