Not entirely how you are looking into this, but I generally do the following:

1) Build an install with the packages and config I need
2) Backup the binary packages
3) Backup all the config files I modified (keep a list during "1")
4) During install at remote site, copy the packages and install using the "-k" 
flag

Any modern hosting site allows me to attach an ISO image to boot from. My 
preference is sysresccd as it is Gentoo based and works quite well together 
with the install guide.
