Hi,
I can do you job in perfection and completeness. I have worked in many fields throughout my career. My last job was a project coordinator cum lecturer on an e learning educational project. I had general works related to project works, in addition I worked on providing audio to e learning video clips for based on developed scripts. What you are asking is vice versa.
Hope the language is clear, preferably UK or US ascent or any other clear ascent. And also hope the seminar is not on hard technical subject. I have quoted based on these assumptions.
Looking forward to work for you.
