Hello Dear Hiring Manager,
I go through your reference website's map filters. According to your requirement i guess you need to find particular store near by and open. So for it, We need list of all stores with there lat long in our Database then we can show them in google and show them near by according to user location. and to manage store you need the admin panel as well from there you can add/edit/delete store.
I am very much interested in this project. I have 5 years of experience in Web-development and testing as well. I can complete this work in 2-3hours. Additionally i can fix it right now.
Warm Regards,
Pankaj Thakur(India)
