Describe the job precisely
'1,000 brochures' can mean anything from thin flyers to glossy booklets. Write the size, paper GSM, print colours, sides and finish - for example 'A4 tri-fold, 170 GSM art paper, 4-colour both sides' - so your quote can be compared fairly and the customer can't later expect something better.
Price flex banners and vinyl by the square foot and state the material, and price cards by the box of 100.
