if your site has 5% house edge, what make your site is better than other site that give only 1% house edge? There are many dice sites that offer really good amount of house edge though. Some of them also put below 1% of house edge
And btw about your referrals, 50% of their wagered that we can get? Dont you think it is too much since you are a new site. How can you pay us really good amount? Unless you have really big bankroll may be it is possible
And about your jackpot? What do you mean by free entry? Everyone knows that jackpot will be hit if we buy some tickets or earn something, so without having tickets how can you get the jackpot?
