Build a website for a consulting firm

Looking for a website rebuild for a small consulting firm (needs to be designed and developed). Current website can be seen here http://www.genesisadvisory.com.au/ and was developed on Squarespace. Open to looking at other platforms such as Wix/WordPress etc. based on your recommendations. Website designs we like are more modern/new-age e.g. https://www.nousgroup.com/ and https://www.pip.global/en/ See file attached for more specific breakdown of pages we want to include. Let me know if you are interested.
