    Hello, my name is David Sharples, owner of Blackball Design, an Australian-based web and graphic design firm. Website and graphic design has been a passion of mine for years, one that I have had the privilege of turning into a full-time career for over nine years now. Having professionally trained at TAFE SA in Information Technology and Multimedia and cultivated years of experience working in the corporate environment and as a solo freelancer, I've developed a diverse repertoire of skills that I've used to help hundreds of satisfied customers. I've leveraged my expertise with the Adobe Creative Suite to produce sophisticated graphics, branding and promotional materials in a wide range of styles. At the same time, I've applied online coding languages such as HTML and CSS and CMS systems like Wordpress to create professional and highly customized web presences. These are skills I can put to use to help you. I pride myself on my high quality service and responsiveness to feedback as well as my flexibility and dedication to client satisfaction, helping people evolve their ideas, bring them into fruition and further their goals and services. Having worked with a wide array of clients locally here in Australia and internationally, I've assisted individuals, small businesses and large companies with projects extensive and small, aiding them with whatever they need. Organizations I've assisted and continue to work with include the Premier Group, International Bullying Prevention Association, CDFS, Macmahon Holdings and many others. Whether you need a logo, business cards or stationery, brochures or promotional flyers, digital or print advertising, including posters and signage, infographics, icons, social media post imagery, photo edits or even a website, new or just help with an existing one, my services are available. Feel free to have a look through my portfolio to see what I can do for you and, if you are interested, contact me and I'll be happy to chat and discuss whatever you need. ABN: 13178662728 менше
