Blogg and Twitter Customisation

I am looking for a designer with EXPERIENCE to customise my blogg background and my twitter background with my photo. The designer MUST have experience with doing this and working with Wordpress and Twitter. ## Deliverables I will be having professional photos taken for this project therefore I require that some guidance be given by the developer if there is any particular format etc that the photos need to be taken in and how the photos need to be provided to complete the project.
