In a survey on the number of Weibo posts made per day by young people aged 18 to 35, let the "average daily number of Weibo posts" be $m$. It is defined that when $m \geq 10$, it is classified as Grade A; when $5 \leq m < 10$, it is classified as Grade B; when $0 \leq m < 5$, it is classified as Grade C. Now, 30 young people who meet the age criteria are randomly selected to conduct a survey on their "average daily number of Weibo posts". The data on the "average daily number of Weibo posts" of the selected young people are as follows:  
11, 10, 6, 15, 9, 16, 13, 12, 0, 8  
2, 8, 10, 17, 6, 13, 7, 5, 7, 3  
12, 10, 7, 11, 3, 6, 8, 14, 15, 12  
(1) Calculate the frequency of Grade A in the sample data;  
(2) Estimate the number of people among 1000 young people aged 18 to 35 whose "average daily number of Weibo posts" is Grade A.
