Here is my rough and ready guide to planning and budgeting for a standard size website;
£0 to £500 Build it yourself or get a mate to help you. Choose an online template build service, there are loads about, though I have used and can recommend moonfruit. I would also recommend using a blog service for some.
£500-£2,000 There are companies and freelancers that specialise in quick and inexpensive build. Find a good one and you will get value for money. Just be conscious of the difference between flat html sites and content management sites. Its cheaper to build a flat html site but that will mean going back to your web designer for every little change. Content Managment System give varying amounts of control back to you for text changes / updates.
£2,000-£5,000 The amount most established SME businesses should be investing in their website. For this amount you will be getting both design & technical support. The designer will help you with the look feel and navigation of your site. A technician will advise you on the best CMS system to use and configure the software to suit your needs. Working together they should consider and advise you on your web strategy, planning SEO, PPC, data capture, email response and so on. However this is only advice.
£5,000-£20,000 When you spend more money on a website you are buying expertise and their time. For this level of spend you will get a full three stage design process, online brand development, bespoke CMS planning, search optimisation, data capture, integarted web strategy (including blogs, forums, social networking advice and email marketing).
£20,000+ At this level of spend and higher your website agency would be delivering a complex site, a tailored CMS solution and / or sophisticated design work, e-commerce facilities, planning of you internet strategy and ongoing support and SEO.
