Personal trainer

Do anyone go to a personal trainer ? I just have a few questions . For 1 , do they work with your schedule? I don’t have a lot of people to babysit my kids so I never really ask anyone . I work Monday-Thursday 10am-6 and Saturday . But on my off days I’m with my kids . #2 . Do they set up a specific meal plan for your body type only? And do they give you a certain amount of time to go by them groceries? #3 how much is a personal trainer ? Do you pay weekly, biweekly or monthly?

And if you do everything by yourself . As in no personal trainer you workout on your own how did you know your body type (I watched a video about different body types and how to lose weight for each , I have a enomorph body type)
