As khun Julie required to make 2 layers of tree , I had revised addition work quote as attached file.
The tree trunk we do texture on steel surface by hammered , about color we can made any color so you can choose later.
Normally, on process before go to production line we have to send drawing approval to client and designer to correct drawing dimension and sign on drawing to confirm to operate. However we can made a sample piece to consider before made the other.
Time to operate about 10-14 days more or less depend on weather.If you require more information please do not hesitate to contact me.
