rebuilding my school's chapter NEED HELP

hi so im trying to rebuild my school's chapter for next year and i need some advice/help on how i should go about it.

we already have people who wanna join and interested events their in but we also have to keep in I’m looking for some advice on how to completely rebuild and structure my school's DECA chapter for the upcoming school year. this past year we had around 40 members but were expected to get like 100 next year, and we also had 16 members go to provincials (were based in ontario) even with little to no structure. 2 of us made it to icdc too so we have a few members right now who definitely have interest in this, but we dont have any structure or organization behind it. the two people who were also leading the chapter this year graduated so i need some help.

basically because were practically starting fresh, i wanna be able to have some sort of foundation for next year and before regionals come up. some specific advice id want help on is the:

exec structure: so like what should the exec team look like, how many execs, task delegation etc.
prep & training: what weekly or even bi-weekly sessions should look like, how we can run case study practice and exam prep
registration: tips for funding maybe?

if anyone has experience in starting their own chapter or even just leading it, i would love to get any advice i can and any guides or resources that you used that I can provide to my chapter or use as a start up. tysm!
