Hello, Greetings! of the day. As mentioned in project description, your requirement is that, the price range values should have a "₦" sign, and the "Area (sq ft)" range values should not have prefix, in advanced search form on your Wordpress website, using Homepress theme. I have checked attached image file. To implement this functionality, there will be some changes required to be done.
I have much experience in working on projects, using Wordpress. Your work will be done, at the earliest, according to requirements.
Thanks.
