1. Web Design & Development - Well of a sort - if you want something really really pretty - better bring it with you. If you want something that looks good enough, is reasonably priced, works and can be found via human words on Google, then I'm that guy. It'll comply with standards (validate) . It'll be responsive, or Wordpress (and responsive), or what you want...Opencart anyone?
2. SEO (Search Engine Optimisation) - This is the best part for me - it's like gambling - you get numbers, you re-spin and you get better numbers, until you get the best numbers.....then well err you look for more new numbers......such fun! Page 1, positions 1 or 2 maybe 3 or I don't bother trying.
Its an Operating System based on Linux. Its free – you can download it now, install it and replace Windows XP/Vista/7 or use it in conjunction with Windows – as I do. Ubuntu has a massive user base, a huge base of supported applications and many of these are also free, released under the same license as Ubuntu itself. Ubuntu has also made new and successful efforts to bring Linux to the Desktop. A very impressive project.
In time I will write some guides to install it and use it and post them here.
