Ah yes, the old "how much is a website?" question.
How much is a car?
Strangely enough cars do have pretty much listed prices at both new and second hand values.
Of course you can be sold a lemon, new and old, but websites are another game entirely.
I spent some time looking for an answer to the "how much ?" question and no-one could answer, though there were lots of proposals to do it for X hundred or Y thousand pounds. Strangely enough, no-one actually said what they would be doing for this money, though I didn't ask the ones asking a couple of hundred as getting pretty much anything started would eat up that budget.
I came down on the idea that you had to decide on a choice between competence or cutting edge. If you want competence, you need someone who can demonstrate they have designed a site previously which does everything or just about everything you want your site to do. However, if you want cutting edge, you will need to employ the creative mind coupled with technical innovators and you won't get them for £10 an hour.
As for my projects, I am still looking for someone but I am teaching myself in the interim, not to be able to do it myself at all but rather to be able to understand what needs to be done and have some more specific input into how to achieve that.
Many websites have their designer's credentials listed at the bottom somewhere and you can then backtrack to their website and see whether they might be in your price range.
