Building administration module for tiki

Basically i need an building administration module. This module will need to be integrated in tiki ([login to view URL]) so its needed someone who has previous experience in tiki. Project details will be established later with the bid winner. Basically i want firstly an time/cost estimation and if it is possible to do it in tiki and have it in an easy customizable form. In short project details are like this: The module will need to allow 3 kinds of users to log in: - building administrators - building tenants/ owners of a specific part of building - site admins Building administrators : - can define a location (data needed will be given later ) - can define number of tenants/ owners - data about each tenant (this must be customizable) ... for all tenants in the building the data should be the same, but each administrator should be able to define different data for tenants in a building. - bills (should be added monthly, and will be more types of bills ..e.g water bills, electricity bills) - generate reports with costs Buildng Tenants - can see only registered bills by adminstrators and reports about costs Site admins - other functionalities (not important right now ...maybe will be subject to other project) ## Deliverables
