If your budget is only 100k, I don't recommend you to do brand planning. You can consider making a website and arranging some exhibition boards and X tables in some places. The general budget is about 20k.
Let's talk about brand planning. If you really don't understand, you can judge from the following points:
1. Is the designed logo simple?
Really good designs are mostly concise, and too complicated designs should not be considered.
2. Does the planner have marketing thinking?
Good design can only bring us traffic, and it depends on marketing to turn traffic into money.
3. Do you have multiple cases?
Practice makes perfect. If there are no cases, it will take longer to solve the problems in the implementation plan. Personally, it is not recommended to choose this one.
There can be dozens of network companies doing brand planning and promotion in Changchun. Wang Ji Media, China Enterprise Power and Aiyi Network are all good. If you can't choose, you can ask them first
