Well, Tim, I'm glad that I already went to an Internet Marketing seminar then and only paid $20. This included lunch at the Holiday Inn where it was held and that was probably worth at least half of that amount.
I certainly wouldn't pay $5000 for a seat unless perhaps it was made of gold and I got to keep it.
What I would actually do if I were in your position is to simply ask God how much to charge for my services. He knows better than anyone what to charge. Yes, I'd do the research first. I also would have to figure in where the seminars are held. In different parts of the country, the cost of living is higher than others.
Moving to Boise, I found that living here is 2/3 of what it was in Alameda, California...where I moved from. So, I couldn't charge the same amount here as I would have been able to there.
For office work there, I was paid $15/hour, which at the time was high even for there. Most jobs there doing what I was doing paid around $12/hour. The same job here pays $9 or $10. And, that was in 2002...so understandably, everything has gone up since that time.
