Hi Holly 02....with a bowl/dish that small, the cost of the raw material is not too important, unless you were looking for a rare, exotic timber. What is more important to know, for me, is what you mean by a straight sided dish. Am I right in thinking that when viewed from the side, the side (edge) is vertical and the bottom flat?
Another factor, before being able to quote, would be an idea of the quantity required. Once my query on the profile is answered, I could quote for batches of 5/10/20 etc, but a guide would be useful.
Regards....Les
