Hi, I work multimedia e-learning for adults projects in last three years. For e-courses I now use recent version of Articulate Storyline (v3) and can create modules you require.
The bid amount is for one module, for the first one to be a test. I would like to know an average number of pages or slides your text based modules have, how many questions/assessments, SCORM or TinCan (LRS) requirements etc. Without one sample it's hard to estimate the scope, time and difficulty of work required.
With 19 years of working career, having my own private business for 5 years and a BS in Computer Science diploma I do not see any problems with the content of your modules.
Looking forward to your reply,
Matt S Rinc
