I Forewarned You,
Nobody, even if they are an expert in the subject topic, should have to spend that much money to listen to someone speak the obvious, in our opinion! Possibly, this was a situation in which the opinion of a professional was not required at the time.
At the very least, the OP now understands the nature of the problem. To find out what the problem is, she will now have to part with her money in order to get it fixed. Then she’ll have to shell out even more money to get it repaired, which will add to her financial burden.
