Does the noise also disappear when you go round corners? If so, that's also a good sign of it being the wheel bearings. However do the tyre swap first and then if the noise disappears, you know it's the tyres.
As for undertaking the job of replacing wheel bearings yourself, then take it on, it shouldn't take very long.
The job roughly entails:
1: Taking the wheel off
2: removing the cap covering the hub nut
3: removing the hub nut **YOU MUST USE NEW NUTS SO PURCHASE BEFORE YOU DO THIS** and spacer.
4. Taking off the old wheel bearing
5: putting the new one on and refitting everything else, ensuring that the nut is done up to the correct torque.
