What specialists are needed to implement the functionality of this service?

Question

MySQL

The event organizer fills out a form on the site: category, location, tags, gender, age, etc.
The user fills out a small form in the android application, which will include form data from the site. Also, the application will collect information about the mentioned tags in user messages.
The collected data is correlated with the specified data of the Organizer of the event, in case of a match, a notification about the event with a description, location, entry price, etc. is sent to the User's phone. If the User is not interested in this event, he rejects this notification.
Statistics on the number of impressions / views / refusals to view is available to the Event Organizer.
Actually, the question is, what kind of specialists need to be selected and with what skills to implement this service?

Answer 1

Well offhand - nothing unique. An architect (or a senior programmer), and ideally a database developer, an Android developer, a web muzzle developer. Some roles can be combined with varying degrees of success.

Answer 2

Who is needed: one person who understands the latest version of Joomla (3.4.x) and PhoneGap.
The cost of all works (without design) - no more than 50k.
