Hello!
I would love to help you to add follow functionality to your blog. I have extended experience designing blogs for both Blogger and Wordpress, and am happy to consider working with other platforms if needed. I also have code libraries ready to use, including CSS styling, so would be able to install these very quickly for you.
I'd be very grateful if you could get in touch to confirm which platform your blog is based on (Blogger, Wordpress, Tumblr, etc), and the timescales you are aiming for. We can then discuss further details from there. I look forward to working with you!
Kind regards,
Simon
