Hello,
I'm Andi, I'm interested to
Let me give you 2 suggestions :
1. Convert your HTML files to be Wordpress.
2. Keep HTML files and make Wordpress separate just for blog (same theme/template with HTML).
For the first suggestion, it will take much more time to input the all contents in HTML to wordpress, and also it will take much more prices.
For the second suggestion, we only need to make a new wordpress theme (same with your current HTML template). But this wordpress is just for blogging and the location is separated with your HTML files, maybe we can make a subdomain and install wordpress to that subdomain.
I think the simple way is the 2nd suggestion, so it will not take much more time and also prices for you. And the price in my bid is for the 2nd suggestion. But if you want something like 1st suggestion, so it will not be a problem, I'm still able to do those 2 suggestion.
Hope you choose me to do this.
Regards
