Wooden pillars for our balcony

[wernerseuros]

Good morning 
 
could somebody give me a tip where and to which price I can buy wooden pillars, for our balcony,  in Buriram. Quality and cost together is my key. The size and quantity should be 14 pieces big wooden column, diameter 5", 76 pieces smaller wooden column, diameter 2½", 22 running meters wooden handrail, size 2" x 5". Thank you for quick response and support.

Regards Werner
