Hi Kinder clean
you need something that you can update for security reason. wordpress is the way to go.
while considering your choice seek out indieweb stuff as this will educate you on owning your content. website are not really about home page anymore. The reason is google and its ownership over the results. plus prospects need to know your url
my advice is upload your database to facebook and market to your customers for referrals and additional services. its cheap. build on what you have. once you start to get ROI on facebook then start to go for new prospects within facebook. The thing I love about facebook is that your competition never knows what your offering, so can not copy. this stops the race to the bottom on price.
you can do some really cool stuff like stories and video
Hope this helps
