BEHRINGER Crossover help needed

I bought online one Behringer 2496 Le crossover many years back , now I want to use it in a 3 way active system :
(Tweeter :Scan Speak D3004/6600 ,Mid-woofer Scan Speak 18W8531G and Peerless HDS 8" as woofer in a separated box )
so the x-over points 2k0 Hz and 400 Hz @ 24 dB
The problem is I am not able to set up the crossover : I took it to most of the stores (in Vancouver ,Canada ) where I live but no
result . I am only 74 ,but my vision /my hands are not good enough to
pick up the soldering iron .I can send it via Canada Post /Fed Ex/UPS to your address ( Vancouver or Seattle only )

Thanks guys ,
