Why do you want MPLS on the top of rack switch?

The Nexus 5Ks are pretty cheap and good if you only need L2.

Do you need 1G, or 10G interfaces, and how many of them?
Why do you need 5? Would something like a pair of 5Ks and FEXs not do what you are after?

IIRC, the HP 5900s only support 16K routes - which could be a problem on an MPLS network.
Can't you just trunk the various VLANs back to a PE/ pair of PEs?

I think the QFX will be too expensive for your budget. IIRC, the EX4500s also have the not enough routes supported issue....
