Depends on so many factors:
- What's actually required? Is it literally just a simple, single page with some text and maybe a logo on it? Or do they actually want a few pages, maybe with some images, perhaps some content they can update themselves, an email form, and social media feeds? (Amazing how "simple" means different things to clients!)
- What's provided for you? Have they given you a design, or any idea of a design? Will they give you images as needed or expect you to make it look pretty without - or find stock images for them? Have they even given you fonts or colours to use? Have they got a domain name and web hosting, or are you expected to provide and setup those as well?
- Your skills and their expectations. Do you have any web design/development experience at all? Is this job above or below your skill level? Is this a "mates rates" request where they're expecting you to do the job for a tenner (and give them the moon on a stick), or are their expectations a little more reasonable?
... and so on.
Hourly rate sounds good - if you know how much to charge. That's a factor of how much your time is worth to you, along with your experience in the field. As dfarrall said above, since you're asking here, you probably haven't done anything like this before? In which case you can't really command a massive hourly rate... but on the other hand, it will probably take you longer to accomplish anything, so your overall quote might end up roughly the same as someone who'll charge a higher rate but knock it out in an hour.
Assuming it's really a simple, single page with no dynamic elements (eg. contact forms, content management system, etc.), and that the business will provide a logo, some idea of a design (at least preferred colours and fonts), and any images that are required... I'd probably call it £50-60 plus the cost of any domain registration or web hosting that's required (which, remember, will be an ongoing cost). If, let's say, they actually want three or four pages to link between (home/about/contact, or something), I'd add an extra £10-20 for each additional page.
But those really are stab-in-the-dark figures based on a few (potentially unrealistic) assumptions!
Not sure that was helpful but there you go anyway
