As a senior technology consultant specializing in information architecture, collaborative business solutions, cloud computing, knowledge management, content management, workflow technologies, business intelligence and social computing technologies, I am uniquely positioned for this role due to my strong information architecture and project delivery expertise. I can re-wriite usable SharePoint workflow to meet the needs you have requested. I would not recommend using .NET/Visual Studio workflows because they limit your upgrade capability. With SharePoint Designer based workflows they are usually supported when Microsoft rolls out new versions of SharePoint. For example, SharePoint 2010 workflows can be used in SharePoint 2013. In the next major release of SharePoint in 2016, it will likely support 2010, 2013 and 2016 workflows as they all have different but compatible workflow engines. Looking forward to working with you.
