If you can work with 7sage admissions consulting, I think it would be a great help. They'll help you determine everything and how to best incorporate your experiences into a coherent narrative that is relevant to law school.
While groups such as 7Sage and Spivey do an amazing job (really!!) I would suggest looking into free routes as well. Are you in undergrad? I know my university has an undergrad pre-law advisor who has been very helpful to me and others!
It would be nice to see a pro/con chart for applying in January.
Are all law schools rolling? Or are there schools that begin application process after deadline?
