Build a Website

Hi, we have recently launched a portal to interact with tech eXperts. Functionality is as followed Employer can post their requirements on the site and freelancers from across the globe can place bids on that project. Once all done, Employer can intact with freelancer via chat and give their bids. The issue we are getting is, once you register on website as freelancer and add your skills you should get an alert whenever somebody is posting job in that category. which is not happening, we need to fix this. Please check the issue and let me know how much this will cost, it seems a small issue.
