I have a client with a site built in Umbraco 4.0.7, its having a few issues with form authentication, and session issues in the shopping cart.
I need the site upgraded to the latest versions of .Net and Umbraco, fix the front end issues and offer continued support to the site on an ad hoc basis.
The source is in GITHUB which I can share once we have an NDA in place.
I am keen to get some idea of your costs to update the site.
I look forward to hearing from you.
