All my website designs are bespoke, I don’t use templates.
As you can appreciate, it is not possible to give you a final figure without first discussing your requirements.
No website comes out of the gate without having the means of earning its keep and bringing new customers and sales to your business.
With that in mind, here are some ballpark figures:
Homepage design along with an about page, pricing page and FAQ page. All copy will be written and imagery will be sourced for you (or you can supply your own images).
All of the above, plus built-in lead generation and blog, along with a simple content management system that will allow you to edit the content on the website. This will put your website on autopilot, generating leads that you can follow up and nurture.
A £7,000 investment includes all of the above but will also allow you to market multiple services on your website. Each service will have a dedicated marketing page.
