How much should mentoring cost?

You do realize that now banks are no longer allowed to overdraft your account and charge you fees without your permission. All banks must be in compliance by July 1st. At that point overdraft fees will be a strictly opt-in program for any transactions using your bank card.

The best mentors tend to be the ones where the relationship forms naturally instead of a simple "pay for services" model. You also need to realize that experience will teach you a lot. Everyone fails, everyone has a launch where in hindsight there were a lot of things that could have gone better, it's part of learning and any mentor worth their salt will readily admit that they are constantly learning too. Make sure your expectations are realistic going in, simply having a mentor in no way guarantees success.

I would also look for a more long term relationship. IMHO just saying you want a mentor for this short project is not really getting a mentor relationship. Think long term success, not short term gratification. A true mentor is worth more than their weight in gold. There's no such thing as a short cut to success, the mentors you're seeking out put in their time to get where they're at and they can't simply transfer that to you.

My best advice to get a mentor is become invaluable to them. I was very lucky to have a great first mentor. I learned exactly what he needed, what tedious tasks he needed done, how he liked things, etc. so he always wanted me helping at his trainings and being a part of all of his events. I can't tell you how much I learned from him and he was so grateful for what I did for him that he worked hard to promote me and my business. It was hands down the best investment in time I ever made because it's that investment that allowed me to make all the others that I have.

I also did everything he told me to do, if he mentioned a good book to read, I made sure it was read the next time we talked. He knew that if he told me to dress in a purple chicken suit and hold a sign with my web address on it I would have done it, so that made him willing to spend the time telling me exactly what I needed to do and how. You wouldn't believe how many people come to me claiming they want me to be their mentor and then they won't do the simple things I tell them they need to do, which means I'm certainly not going to spend the time telling them the deeper more complex things to do, it's a waste of my time.

So I guess my long-winded point is, you are much better served by finding a true mentor relationship, not just someone to quickly help you with this project even though immediate needs tend to dominate our minds. I doubt a thread on this forum will put you into a mentor relationship, but it may put you in contact with someone that over the course of the next few months might become a true mentor to you.

Good luck on your endeavors, sounds like you have a great start! Don't be scared to just go for it with this first product, if it doesn't work you can regroup and have another go at implementing what you learned the first time.
