Are UK rates really that much lower than Dutch (NL) rates? In my experience (both as a freelancer and in hiring freelancers) is that in all areas of web development and design hourly rates start at €40 for wordpress stuff (charging less would be considered amateur range) up to €120 for really specific skills with most developers and designers charging around €60-€80. Even with these rates it's pretty damn hard to find decent Python/PHP/Ruby or front-end devs. Designers (and Flash devs) are a bit easier to find as we are not lacking design/art schools. Could it be there are simply more technically schooled people in the UK driving down prices?
