Hello
I am Mahesh from India. I have great experience in web development.
I read you project. You want clean, responsive, beatuiful website for Real Estate. And as you mentioned you seems to be used Mobirise. And you want to make improvement in existing site.
Let me tell you few things.
As per your requirement, you should not go for Mobirise anymore. We have many options for the site which you want to get delivered. We can use WordPress instead.
The most important part is, we can use many features with the help of plugins. Like security, chat, lead generation, social media connectivity, pro themes, SEO, caching, etc.
You can also handle the site from your end if you want so.
I have used Mobirise and it is simply for them who want to use ready section for very small site.
You can ping me and we can discuss about the project in more detail.
Thanks,
Mahesh
