In some cases there are no 'off-the-shelf' solutions and creation of custom coding is required. We can provide such a service including database design in enterprise standard configuration.
It might also be that an opensource CMS will suffice with only a small portion of custom content required. Such an add-on to an existing content Management System we refer to as a Module. We have produced many such Modules for a variety of CMS types some of which have been released publicly under the GPL license. these can now be found scattered around the globe on a wide diversity of sites.
Costs, as always, vary greatly depending on your specific needs so we need a clear and concise understanding of what you need to allow us to draw up a plan and give you a figure. The first thing you need to do is get in touch. you can do this easily through the Contact form on this site.
