Promotional flyer for interpreting services (in Japanese and English)

We need an A4 size flyer describing our interpreting services. The flyer is for our Japanese and non-Japanese clients, so both languages will be on one sheet (possibly front and back). We will provide the copy in both languages (English and Japanese) and a logo.

We are looking for a long-term relationship with someone who can handle graphic design, layout, and pre-press processing as the need arises. The graphic design will mainly be for our company promotion, while layout and pre-press processing would be part of the printing process (a service that we are also offering).
