A skimmer is not ABSOLUTELY needed. It would help, but i run my 75 gallon without a skimmer. I also found my live rock on ebay for ~$2 a pound. Much cheaper than paying $5/lb at the LFS. Since your doing a FOWLR, you won't have to spend too much on lighting.
For my 75 gallon i spent:
$200 on live rock
$50 on Compact flourescent lighting
$10 on sand (playsand from home depot)
$30 on salt to fill it up
~$280 (without fish)
And thats about it. I had a couple canisters laying around so i used those. I spend about ~$4 a week to do water changes with RO water.
