This may be a bit mad but have a look on Gumtree etc for desks or office equipment . I sold an office desk a few years ago for next to nothing. Really couldn't give it away. Use the tops and bin the rest.
Another somewhat odd suggestion is IKEA. I've bought an L-shaped desk for my daughter from it. You could get matching stuff from there. I should say that the desk I got rid of was 1000% better quality than IKEA - heavier and better quality but you get what you pay for - sometimes!
