Giant Reed, Bamboo and Palm Fronds Wanted for Building Materials - $1

My son and I are looking to build some structures entirely from local materials.
We are currently looking for sources of Giant Reed (arundo donax), Bamboo, Queen Palm Fronds and California Fan Palm Fronds.
We'd happily come cut, clean and remove any unwanted materials in return for taking them with us.
Email us with details if that would be of help to you!
