What you want is a bandshoppe pole. There is a supplier here in town, i'll look into it friday and let everyone know how much they charge. From what Konradr/Taco said, it's between $8 - $15 for one pole (ranging from 5ft - 8ft)
the actual cost plus foam + glue would be under $20. You wont even need a full roll of blue for the spear, hafting included.
By arm shield, do you mean a buckler?
Also, dagger does only green (stabbing) damage. Did you want that or a short sword/blue?
