plywood log

Dear Sir/MadamI am looking for between 10-12 cm diameter logs. Especially when you manufacturing plywood, after peeling of logs,you get rotary waste of log,I want these logs. The quality is possible 2nd,3rd or 4th grade,not crack!!! The kind of tree is not important,should be cheap for me. The length is possible 100,120,180,200,240,280,300,320,380,400 cm...(mixed also possible). I need 300-500 cbm every month(at least). This is a serious business,like you see our standards are very easy,so it should be very cheap. Buying is possible according to unit or tone calculation. If you have another lengths or diameters, please let me know.Best RegardsOrcun Engur
