Creation of a photo collage

I have a collection of private photos (approx 20 - 30) from a recent trip which I would like mixed together to form a single collage image that I will have printed in high resolution for framing here in Australia. I want someone who has done similar projects in the past and has a good understanding of how to mix and position photos in a final design that will be visually appealing. A small example has been provided, however we have many more images. The final image/collage will preferably be in a panoramic size format with the print to be clear at a print of 30cm (height) x 100cm (width). I would like the words "Kokoda 2010" inserted in the bottom centre area of the image. Images will be uploaded to the successful applicant in JPEG format with the final product preferably in the same. MAXIMUM BUDGET FOR THIS PROJECT IS $30 AUD. Bids over this amount will not be considered.
