I would suggest that you capitalize; I like the look. Do not, however, use periods unless you are bulleting complete sentences.
Also, in introducing the bullet points, use either a colon (formal) or an m-dash (informal) but not both.
More importantly, be sure that the items in the list exhibit parallel structure:
- Modifying the building and office equipment - e.g 'placing a ramp outside'
- Positioning certain staff on the ground floor, if no lifts are in place
- Being flexible with office hours and time off for e.g medical treatment
- For Teachers
