The only thing I can think of would be market experience i.e they've worked somewhere in the industry you're targeting.
MBA itself does not give you the skills and most importantly experience.
I expect selling to VCs requires a certain amount of posturing and hubris but doing some Customer Development should be possible for anyone. Customer Development is not sales. You might find it difficult at first but when you realise you're offering something of value to someone it feels a lot better.
Unless you can reveal what market you're in, the advice you get here is going to be pretty generic. If we knew that you were interested in $FOO then a few folks might know about $FOO meetups or conferences that you could attend. Also, bear in mind that you will still need some sales skills to convince a someone to join you.
I guess I could try doing everything on my own, but due to some circumstances I really need a partner. I'd rather not convince anybody to join me. Maybe it's naive, but I think if a person believes in the idea and the skills I have - he/she will want to join me without any persuasion.
I'm also OK to join somebody if he/she has an idea I would be interested to work on. I realize that my idea could be just a piece of crap and I did not realize it yet.
