Obviously logo, colour & images are changed for to match the type of competitions you are having. Also, albeit not much text within the site, this will need to be supplied by yourself & we will add it to the site.
We are experienced in what works within competition websites & we will advice you in this, but at the end of the day its your choice.
Added features can be added at extra cost if they do not conflict with the competition plugin.
We are flexible in what you need & small items changes we usually do for free or minimal cost.
