Dear Sir,
I think the budget would be increase by the number of illustrations.

Thank you.

How much you reckon it should be? Thanks.

Thank you for reply.

I think at least 15$ per simple illustration.
Sorry with my confusing.

Do you mean $15 extra for each illustration? I only have about 10 illustrations, I will remove several in document 6. I will revise the documents if it is allowed.
