Can anyone recommend a reputable company for a Oahu Destination Wedding?

My Fiance and I are planning a destination wedding (with abou100 guest attending) I have researched so many wedding companys that offer beach wedding packages. We are planning a reception following the ceremony. Can anyone recommend a company to provide a beach front wedding (minister, flowers, chairs, photography etc) that reputable? We are looking for quality and professionalism.
Also, any recommendations for travel agents or company that can provide my wedding party and guests with decent pricing since there are quite a few people going? Great group rate discounts?
Thank you, I just feel like there is so much to do and I don't know where to start.. (I haven't even chosen wedding colors)
I have reserved the "Halekulani Hau Terrace and Lanai" for the reception but have a week to give the deposit. Has anyone used this area before or suggest otherwise? Thanks..

I'm surprised that the Halekulani can't give you someone to help you as part of their service - lots of hotels will. Get a wedding planner - here's a link or two - check out Hawaii Bride mag's also

Hawaii beach weddings are great. Ive heard of Lanai and seen it on the tele too. Check out the websites for both the places you have reserved and find out all the first hand information on the net.

Hands down, I recommend RC Anderson

Tell him Pastor April sent you.

My hubby and I used www.wedaloha.com. We had a much smaller wedding, but they did a great job and walked us through everything from start to finish. And the pics were STUNNING. Can't recommend them highly enough. We got married on Waialae Beach, and it was gorgeous - but they do offer several other beautiful locales if you like. Congrats, and good luck with your planning!
