have you ever heard of these folks?http://www.transglobalexpress.co.uk/
i used to work in freight so you might want to look at 'freight forwarders' as anything over 32kg is 'overweight' when it comes to courier companies.
I did a quick calculation for you using the transglobal website,
i assused certain facts, ie your 4 x parcels will be picked up & delivered within the uk, each parcel weighs 30kg (x4) and the dimensions of each one is 30cm x 30cm x 30cm. I chose Portsmouth as the pick up as i wanted somewhere far (enough) from the Wirral.
Quote came in at £78.15 +VAT (it's just an idea of price but I am assuming that is door to door delivery).
ONE THING - about Transglobal, I think it's credit card only (not sure but you can check on that).
Oh and they are (or at least used to be) based in Bromborough.
