Search Feature for Events from Multiple Sites

Hi Freelancers, We would like to have an event search feature for our website, in which we include events published from specific cities. See the list below These events are currently available in different sites, and we would like to have an easy search to get nice appealing search outcomes in one place. We are currently considering 3 main websites for that matter. Each site, has categorised the events in its own way, categories such as Family, business, lifestyle, entertainment…etc In addition, to the above automatic method, we would also like to have the same solution with a manual option as well, were we can also insert specific events. We don’t have our own website for this search feature now, however it is in its way. Appreciate your proposals detailing the best way to tackle the above request. Please let us know if we need to change our thought process for this project for any unattainable objectives, we are open for any new ideas as well. The 3 sites we are considering here are: o [login to view URL] o [login to view URL] o [login to view URL] kindly share your proposal in plain and easy english ( we are not Techies !) Thanks & Good luck to all,
