We can be really honest here since there is little conflict of interest. The website design cost largely depends on your specifications for the website features. ( The rates are in Singapore dollars )
a.) If you want a simple website design without much customisation of where the text and images are AND you have a cool 7-14 days to spare, using a theme or following our guide on how to make a website can probably save you thousands of dollars.
b.) If you want a slighty customised website that has a blog, a contact form and some beautifully custom made design elements, this can set you back at a range between $1000 - $5000 maximum if it's a Wordpress build. ( You should really be using Wordpress because it is SEO friendly and it allows you to change things by yourself, saving you money on maintenance. )
c.) If you want a really customised website with specific features such as user login, allowing users to perform specific functions, you could be looking at a minimum of $10,000 and the sky is the limit for this depending on how many features you need to build.
If you are a local business looking for leads or online sales, option b would be our recommendation.
