We use WordPress at Vision Marketing, it is great !
At the end of the website build you will have a back end that you will be able to play with and change yourself! This will really help your budget and allow you to be in control. For any quick changes you will be able to dive in and do yourself, this take away the expense and the headache of waiting for a developer to do it. Of course if you get stuck we are always here to help.
WordPress is a free open-source platform, however as with anything it takes a learning curve to get to grip with it, you can either have a go, or to save your self a lot of stress and time, let us put a great site together for you for just £299!
