Ongoing leaflet design work

We look after a small print broker business looking to expand to offer clients a 'we can design your leaflet' service as well. The intention is to offer a fixed price design service where customers would submit their rough ideas (as a word doc or email), together with any of their own pictures, and we would produce a design for their approval, which they would then correct (once only) before re-approval and printing. We would like to appoint one or more designers to produce the designs on a fixed 'per job' leaflet - based on a double sided A5 leaflet. You may need to add additional images / backgrounds / textures etc from the likes of istockphoto, we would pay for these in addition (or give you a log in to our account). Turnaround from us sending you a job to the finished first draft would need to be 48 hours or less. For the purposes of pricing, please provide a price for a 'contract' of ten double sided A5 jobs, with the results to be sent as a PDF and an Indesign file where required (ie whatever price you suggest will cover the first ten jobs we send you) You MUST provide either some samples showing the range of work you have done, or a link to a portfolio or website. Submissions without these cannot be considered. We expect there to be a good stream of ongoing work for this, and also for their to be other sizes/ type of job (at other prices to be discussed).
