Can someone help me

[Lee Freya]

I need help with my grenade quest. I'm almost a lvl 25 and i still havn't even gotten past the first part. I've been doing other things, mainly the story quests. as of now i have all the charcoal and 8 out 10 saltpepper. 1 sulfur and i don't kingshead that well, i usually get lost and die. so your help would be greatly appreciated. i might need your help for the whole quest. I'll do as much as i can though. thanks in advance.
