Hello,
I have been a blogger myself and understand the importance of clean and targeted design for blogs, but sharing your blog URL would have been good, as we have to analyze the amount of work needed to be done on your website renovation. We will go through the content an pages of the website and provide you an exact time frame and budget after that. The design of the reference site can be replicated and we are much capable to provide you something better than that.
We can even design logo and headers, as we have a experienced designer and we can dedicate him for your project once we are clear with the complete scope of the project.
Lets discuss things further and we can then decide the things accordingly.
Hope to hear back from you.
Regards,
Mayank
