can you invite them in waves? send 500 invites, see how many join on day 1, maybe assume 50% more will join over the next week. Repeat to get to the number you want in the beta.
also, many will sign in once or twice and never come back. not all beta members will be active members.
Be open & honest with those you turn down. until you can invite them, keep them in the loop with a periodic newsletter. maybe even poll them if you need customer input.
