Kill Weeds ? Need Real Help?

Question:Ok we just bought a new house and we are going to put in a pool here soon but for now we need weed control. We do want to put grass in but for now it's a waste of money just to have a tractor or whatever other equipment tear up the lawn ... it will be a month or two but would like to use something that works as the lawn is getn over taken by weeds.

Please please please help me :-)

I have used concentrate roundup and others but still slow going ...

Answers:
Tractor Supply Co. has a type of weed killer that they guarantee will kill the weeds but will not kill your grass or flowers. I'd recommend using that.
