Kerbal Space Program: Getting the SRB-KD25k "Kickback" to orbit?

In KSP, I have a contract to test the Kickback SRB in orbit. That seems impossible to me, how do I get a huge SRB like that into orbit? Remember, I can't light it up until it's in orbit or the contract isn't fulfilled. Also, I only have up to the third tier (or fourth if you count the "start") of technology researched plus Heavy Rocketry in the fourth tier.

How do you put a rocket into orbit in KSP?
Steps to Orbit and BackHow do you get back to orbit KSP?
If you have any fuel left, rotate your craft towards retrograde and burn until periapsis is below 70 km. If not, send a craft with a Klaw up and rendezvous, and then refuel the craft with that. If you have re-entry heating low, you could EVA and use the jetpack and parachute to land.How do you get out of orbit without fuel KSP?
Get out and push!Go on an EVA, activate the jetpack, and fly against the prograde-facing side of the capsule. When you are nearly out of EVA fuel (right-click on the astronaut to check how much you have left), get back into the capsule and leave it again to refill. You can do this as often as you want.Testing the S1 SRB-KD25k \
