If you looked at the homes, like yours, that sold since July, what would you find? Do you know how many have sold? Lots probably.
You don't need a motivated agent. You need a seller who is motivated. Motivation is defined as "needs to sell".
If a home sits on the market for nine months, any buyer will tell you that it is over-priced. Rather than blame the agent, who perhaps was not aggressive enough with you, the seller, take a more positive approach.
If other homes are selling, then why not mine? Ask your Realtor that question. If they cannot answer the question, then you need to ask them "If I hired you to sell my home, and you don't know why it's not selling, what do you think I should do?"
There are very few problems in the sale of a home that a price reduction will not solve.
