Asterisk system engineering

I need someone who is skilled in asterisk and PBX in a Flash to be able to log into my system and create IVR scripts as well as just make my system perform up to what I'm sure it can do...I would like to use my system both for my small business as well as for my home, and I already have it up and running on Aterisx 1.6. Specifically I need someone who can: 1. suggest how to log into my system remotely through NAT or be able to supply scripts for me to enable 2. create IVR menus - I need 3 - one for home, one for business, and one custom - I will create the recordings locally 3. I already have a Vitelity trunk with 3 incoming lines - make sure that they are set up properly 4. I want my 1 incoming home line to have its own very simple menu response (just to keep out robo dialers) 5. Set up my ring groups so it dials out to respective cell phones (2 of them) I am on vacation from the 27th through August 2nd but maybe we can achieve this prior to me leaving on Monday...but no big hurry. I'm hoping and thinking that this should be very simple.
