Just sent out first offer to to build a simple static website. Did some web searching to see what other add agencies were charging for small/medium sized static sites. Lowest starting points were even as low as AED 1000, though more often around 2K – 3K AED. These are the lower end though and probably would not have been designed that well. Even their own websites were not nice. Price goes up 2k – 3K if the websites need a CMS. Found a more decent agency which said it charges 12K – 15K AED for small corporate static websites.
Also read an article about deploying React apps to AWS. Basically they are saying the way to go is to use create-react-app, and then dump the contents of the build folder into any hosting site you would like to use, be it Amazon, Heroku, or something else.
