I haven't written detailed description yet but here is the outline. I am taking an estimate on amount of work to be done and prefer if you ask me questions and I answer.
Here's the list of things I need in my web portal
1. Chat functionality - IM functionality
2. Task Management - Check "redmine"
3. Online repository (version control) - check "github"
4. Calendar functionality - standard
5. Profile Management - standard
6. Invoices ( only bill view or generation). I do not want payment gateway. - simply converting hours to amount and fill in standard pdf template or export in pdf format.
I just need an estimate at this point. I don't mind if your quote will go 10% up or down.
