I put it into a garage to have it done since I don't have a lift, but no, it's not a huge job. 2-3 hours if you're a first timer with some mechanical experience at most.
I paid 230 for parts, and 130 for labour (+ some small parts and fluids)
Front bearings and oil seal
Front shock seals, covers, clips and 465cl oil x2
Front brake pads
Sprockets, chain replacement (DID Gold X-ring, JT sprockets)
Rear brake pads
Rear bearings+seal
Valve check
Oil+filter replacement
Carb check (no work needed)

At €15 an hour, might be different in the UK.
