You only need 300 yuan to apply for a trademark. How much more do you want from the government? The official fee for registering a trademark is only 300 yuan.
Then you must have found an agent. The agent told you there was a subsidy. Then see for yourself how much the Trademark Office can subsidize by charging 300 official fees. Just apply for it yourself in official website, China Trademark Network, and you only need to pay the official fee, which is much better than finding an agency to spend 2000 yuan and give you a subsidy of 100 (this subsidy may be made up by the agency). Does being a boss count?
Two options:
First find an agency to help you register, spend 2000 yuan (no matter how much, anyway, a lot) and then subsidize you in 200 yuan.
Second, if you apply in official website, China Trademark Network only needs an official fee of 300 yuan, and will not register a tutorial with only a few dozen on Taobao.
Then you do the math. And looking for an intermediary has to worry about being cheated.
