How to Estimate Costs for a Mid-Level Interactive eLearning Project?!

Hello eLearning Experts,

I’m working on an eLearning project with a mid-level interactive design that includes:

• Videos created using Vyond
• Development in Articulate Storyline
• Graphics designed in Adobe Illustrator

I’m handling the entire project lifecycle, from concept to final delivery.

I’d like to know:

• How do you estimate the cost for such projects?
• What is a reasonable cost per slide or minute of content for this level of interactivity?
• Are there any specific factors I should consider (e.g., complexity, review cycles, or client changes)?

I’d love to hear your insights, especially from those who’ve managed similar projects.

Thank you in advance for sharing your experience!
