I’m in a bit of a dilemma and could use some advice. I’ve been approached by an NGO to develop their website. They don’t have any knowledge about hosting or domains and have left the decisions up to me. Here are the main points I’m considering:

SEO Importance: Their main goal is to have the site show up prominently in search engine results.

Development Options:

Custom Development with React: I can develop the site entirely myself using React, but I’m not very familiar with hosting on a custom domain or optimizing for SEO.
Website Builder (WordPress/Wix): I can design the site using WordPress or Wix, which might be easier for managing hosting and SEO.
Cost Estimate: They want an estimate of how much each option would cost.

Questions:

SEO and Hosting: How difficult is it to manage SEO and hosting for a custom React site compared to using WordPress or Wix?
Cost Efficiency: Which option is likely to be cheaper in the long run considering both development and maintenance?
Best Choice: Given the context (NGO, lack of technical expertise, emphasis on SEO), which option would you recommend and why?
Any advice or experiences would be greatly appreciated!
