Hello Sir,
This is Pallavi from Amenda Technology. Have gone through the requirement and we can suffice it quite easily. Even to add on, we can have scheduling supporting in all time zone, for example, even if the application is in US timezone, u can schedule the mail responder in any timezone. Personal scheduling and portfolio t manage self documents for each sales rep would be a addon feature that we can provide. We have done similar stuff for another client and can do it easily for you as well, will not be a proble.
Technology wise we will use JSF, SEAM & Hibernate to be main frameworks to support a robust and highly maintainable application.
Cost is the factor that needs to be rethinked, 250$ is way too less for this project. lets discuss on all if the proposal intrests you.
