According to my calculator you are going to need 267 Lbs. of seed per acre or 6 Lbs. per 1000 sq. ft. That would be ideal if you had irrigation. Since i don't think you do you might want to consider 8 Lbs. per 1000 or 356 Lbs. per acre. 100 Lbs. per acre is way to light. You need to use the best seed possible for your area. http://www.ntep.org/
When you do seed put down the seed, fertilizer and lime all at the same time. Use pelletized lime for this. You probably need lime but get a real soil test first, don't guess at what you think the soil need's.
Don't use pre-emergent herbicide until your new grass is well established. That usually mean's the following spring.
Do you have the proper tool's to do all of this ?
