Can anyone recommend a courier? Need to price for sending a shower screen

[Tobermory]

Never couriered anything before and no idea where to start!
Have tried 'pick up' only and no joy and it needs to go!

www.parcel2go.com

Used them recently, v impressed!

due to the size of a shower door alot of couriers wont take it also is it glass?? Parcel force will take the larger items I use www.senditnow.co.uk as they dont ask about measurements just weight
