Hi,
From what I understand you need to implement the back-end functions of an ionic template you will purchase. The back-end is based on wordpress and you need Login , Registration , Getting properties list, Getting details of a property and Contacting the agent features.
I can help you on this . I am immediately available to work on the project and it can be completed by 7 days maximum.
Feel free to contact me via chat if needed.
Best regards
Emmanuel
