Pipe clamps are way cheaper than parallel clamps and still work very well. But are still pretty expensive if it’s really only for a single use.
You can get a lot of clamping pressure from a couple of wedges. Screw two 2×4s down to your workbench or a sheet of plywood slightly further apart than the wood you want to glue up. Make wedges that are smaller than the gap. Put 2 wedges together the way you do with shims. Do this in several places along the length (the number will depend on the width of your pieces – wider pieces need fewer clamps or wedges since the force is spread out more). Pound the wedges toward each other until you get glue squeeze out along the joint. Allow the glue to dry and you’re good (you should probably protect the plywood or workbench or else your glue-up will stick to it permanently since unlike with clamps you’re gluing directly on top of the work surface).
