We do consulting, staffing, and the last few years a lot of training around project management, business analysis, leadership, Data Analysis, Lean Six Sigma, and other misc topics. Corp Govt Nonprofit, all size firms, all over the world w/Austin TX local open enrollment. We are seeking service providers to produce some generic (like certification prep and intro stuff) courseware while we do the advanced best practices courses. We would also like to partner with service providers that list our courses and help us sell them for a commission. We would like to have more students in our open enrollment courses too. We are NOT after generic web/marketing services, rather providers or agencies with specific knowledge of training courses and the ability to market our courses world-wide. Where should we go to find what we need? We are considering VMEdu, SimpliLearn, Vertical Distinct, amongst others.
Have you considered using OpenCourseWare to address the gaps (Coursera, EdX, Udacity, etc)? I've had large global organizations move from SkillSoft to OpenCourseWare to fill their curricula.
The bigger question is: Why doesn't your organization provide the generic/101 training for the topics in which you provide advanced training?
