535810 Joomla Website and Extension - (Php & MySQL programming 2

I have created a Joomla Website and installed all the necessary extensions and plugins. Basically you need to modify and customize the functionality of two Joomla extension I have already installed . Some of the configuration can be done within the extensions itself but you also need do some custom programming to create some functionality. The two extensions are: - DOCMAN (Document Management System): [login to view URL] - AceSearch Extension I've also installed another extension called PDF Indexer (which indexes all the content of the PDF) and it's working fine right now. The goal of the project is when we upload the documents through DOCMAN (Component), in the fron-end where it shows all the folders of document, users will have access to their own file. Requirment: - Right now When you upload a PDF file form the Admin (Docman Component), the PDF INDEXER Component indexes all the PDF Content in a database which is searchable on the front-end(this part is already done), but below are the things we need to fix - Search Box (AceSearch Extension): , You need to fix some issues. when we search using the "Search Docs" (AceSearch Extension)in the front-end, it searches all the PDF content and displays all the PDF files that matches the search, (this part is already done too). But other stuffs that we need to fix are: We should also make sure that the permission will restrict the search. For example if I'm logged in as a Group A user then when I search for a PDF document, it should only show the PDF that's allowed for Group A. And there's few other stuffs that's not working properly which I'll discuss. - DOCMAN's PERMISSION(For Multiple Group): We need to change some functionality in the way permission works, For example we should be able to assign permission for a particular documents or a Group of documents for multiple users or multiple user group, which means if I have a documents in "Folder A (Category)", I can assign that document category to be downloaded by multiple group of users: User Group A and User Group B but not to User Group C - WEBSITE DESIGN: You don't need to design yourself but I'll provide you with a design and you need to integrate that design with the website, we'll do the design changes at the end once everything is done. - Beside this requirement, some other small functionality changes might need as the project starts (around 20%) Optional Features (which we might need later but not now): - Ability to view the PDF Online (Optional) - Allow users to choose notification method of new docs (Optional) - Allow user to change their Login Password (Optional) I would like to finish this project as soon as possible.
