It's hard to give an estimate when we don't know what you want, but as a rough guide:
₤175 / €250 - Up to 4 pages
₤240 / €350 - From 4 to 10 pages
₤350 / €500 - 10 pages and above
You supply the text and pictures you want included, and we put it all together in a nice way. We can also design logos & site graphics etc for a small fee. If you simply require a template, and intend to add additional content yourself, we charge ₤150 / €210 per template.
This really depends on what you want, so let us know and we'll give you a quote. But just as a guide, an average Flash banner advert or animated header will set you back around ₤35 / €50. Full Flash sites will obviously be dependent on the amount of work involved.
As SilverStripe is a free CMS, we won't charge you for it, so you'll only be paying for the template. We charge ₤150 / €215 for the template, and a one-off setup fee of ₤100 / €140. If you require us to handle the hosting of your SilverStripe site, we'd be more than happy to oblige (for an additional ₤40 / €60 per year :oP).
We can also host your website for you for a measly ₤40 / €60 per year.
