Joomla Component modification and Mobile apps integrated

Already have a Website powered by joomla, and need to modify a buyed commpoment ABProbooking, used for appointment booking online. Background: The joomla website will be used for Hairdressers , Salons, And beauty professionals. The main porpose of the website is to give the hairdresser a website for publishing theirs services, products, specials, bio and background, and finally oferr the posibility to their customer to do online appointment booking, using existing joomla component. This part of the systems is already working and don´t need to be developed, just explained to gain some background on the project. This are some of the features need to be builded on the compoment (appointment booking component): The compomentn actually has the functionality to schedule appointment to registered users of the joomla website. now We need to add the functionaliyty of CLIENT RECORD, for this porpose we need that for every single user that is registered in the systems, we will keep a record of the services history. For that purpose, we need to add a Service Record, that will be filled by the hairdresser using a mobile App that will be integrated to Joomla compomponent, optionally the hairdresser could use the joomla frontend to fill up the service record. CLIENT PHOTO GALLERY, for every single registered client on the system, we will keep a Photo gallery, registering all the photos taken during the services usign Mobile phone app. This can be part of the existing componet or can be a new component used for the purpose but need to be integrated to the joomla users profile. Mobile APP: ADDRESS BOOK: The hairdresser wil have the choice to use an mobile app (IOS or Android), were they can query their client database (joomla integrated registered users), udated the database with new clients they get on the road or from their phone contact list and import and register in joomla. SCHEDULE: The hairdreser will have the list of appointments scheduled usign the joomla component, can add new appointments, and can Accept or reject scheduled appointment by the clients usign the joomla website. SERVICE RECORD: The hairdresser can fill up the service record, using their phone, do the client check in, and check out, fill the diagnostic, and the recomendations, take pictures after and before and upload to the Clients Photo Gallery. And checkout the customer and get paid. Required Skills: JOOMLA, PHP, JSON Web services, Sencha and phonegap for the mobile apps part. Atached is the userguide of the component for booking online.
