Graphic Design - Brochure, Welcome Booklet and Postcard

I am setting up a Fruit and Veg Box Scheme in the North East of England. I will be delivering locally sourced fruit and vegetables direct to customers. I have developed my brand identity, colour pallet, vehicle livery and I am now in the final stages of preparing my website for launch. I am looking to work with a Graphic Designer who can develop the following marketing materials for me - a promotional leaflet, welcome booklet and A6 postcard. Promotional Leaflet to showcase my products and attract new customers. This will be delivered to new prospects at events and through a leafleting campaign. I want to introduce the business and my products, leading to new customer sign-ups. The leaflet must be cost-effective to produce while also standing out on the doormat. Welcome Booklet - an addition to the first box delivered to every new customer. This will welcome them as a customer, give hints to make the most of their deliveries and set out how the service operates. An A6 Postcard - I will operate a refer a friend scheme with all my customers which offers a reward to both my new and existing customers for every new signup. The postcard will be a general info leaflet that will be periodically dropped into the boxes.
