Magento Customisation - System Configurator

General information for the website: We sell server / storage hardware. Kind of development: Customization of existing website Description of requirements/features: We have a product configurator on our Magento website for our server systems, it works and it's okay but one of our competitors has a more easy to use, more detailed configurator, it's better. We would like our configurator to be more user friendly and be more detailed like our competitors, I will provide links to both. We're not trying to reinvent something, It's exactly the same concept so it can almost be copied but styled a little different. You'll have to insert the code in our website as well. Please quote an accurate cost and time frame. If you have done a similar project before, please provide examples. Extra notes:
