Well... places like Daniel Dean, https://www.danieldean.com/, and Kat Excavation, http://katconstruction.net/, would do it for you. They'll charge you an arm and a leg. A cheaper way is to hire Red Stag, https://www.facebook.com/redst..., - they'll come out to you, but they'll only do the lot clearing and grading. Then you hire a dump truck driver, ask him to get two or three buddies, and tell him to haul off the dirt that Red Stag digs up, and when done, bring in new dirt. You gotta find a sand company for them to go get the dirt from. They are usually companies located near rivers, like the Brazos. Or the dump truck drivers can tell you where they've gone before. To find a dump truck driver, you just have to drive around your area, and when you see a dump truck, look on the side of his truck and you'll find his company. Almost all dump truck drivers are small owner-operator companies that don't have websites etc.
When you say "scrape the pad and bring in dirt", I do hope that's based on engineering specs. Ideally, you should have a soil test done, and then based on that result, you'll know how many feet of dirt to take away and how many feet of "select fill" to bring in, so your future foundation doesn't buckle or shift on our expansive soils. Also, this is the time when you need to raise your pad above the surrounding soil, so you'll want to make sure they do that. Feel free to reach out to me if you have any other questions.
