Although my web design skills do not extend to the ability of being able to scratch-build sites using CGI / PHP / ASP code, but at least being adjust bits of it as needed when doing installs of popular scripts, I can still offer you sites custom built using this method by sub-contracting it out via one of the Freelancing websites out there.

As these sort of websites are rather more complex to develop & get working than regular HTML websites like this one you’re looking at, pricing on these are a case of POA (Price On Application), but I’d probably budget from anywhere between £200 to £10,000+
