We require an extension for our Joomla website (version 3.0) which will provide our customers with an instant quotation based on their selections. We are a furniture rental company, with different rental packages available. We require our customers to select a package, and then be able to further customize that package by adding or removing specific furniture items, with the required monetary total adjusting in real time as items are added or removed, according to the amount of time they would like to rent for. Once the selection is complete, they should be able to have an invoice generated, and then have the option of paying online should they wish to.
We should obviously be able to have a simple interface in the back end to be able to update our stock items according to what is or is not available at any one time, and we should also have the ability to adjust how furniture items are bundled together, ie: be able to add or remove specific things from each package, or create new packages.
You will see by the images attached how we envisage this extension to work - each package being merely a pre-set arrangement of what furniture items first appear in the quotation, and then the customer can add or remove items form there (the pre-set packages would merely be 'pre-set starting points' in what first appears in the quotation).
We expect to be able to work directly with you, working hand in hand and in constant communication via skype throughout the development of the extension so that there is minimal room for confusion and error.
