WANTED You Tube Background Music - 10mins of music for £20

BRIEF SUPER QUICK SUMMARY

before you get bogged down in the detail - please listen to this YouTube link. I want music like this but a bit happier a with a recognisable theme/tune that recurrs occasionally in different forms.

-------------------------------------------------------------------------------------

I'm making YouTube videos. It is very difficult to get copywrite-free music to use in the back ground

this is the brief:-
1) no drums or heavy beat
2) no major changes of volume level
3) slow, chord-based, pleasant, soothing melodic vamp with maybe a theme that recurs occasionally. Perfectly happy for it to be based around a Beatles song, or pop song or classical music - so long as it doesn't trigger copywrite issues
4) no silences
5) nothing too intrusive - no high pitched guitar licks. no high-attack piano themes. Gentle lower register is fine - but synth keyboard with low attack might be better
6) about 10 minutes long
7) I'm not looking for perfection - it's a background music bed
8) not expensive!

Im perfectly happy for it:-
1) to be improvised and made up on the spot and recorded in one take and then perhaps add a synth, bass track or chord track after. Synth type keyboard would be fine - but not with piano attack
2) for you to sell it to other people also - so long as it doesn't trigger any copywrite issues for me on YouTube
3) for there to be quite a bit of internal repetition.
4) for it to be reconisably (but not triggering copywrite) an improvistion based around a Beatles song or pop song or piece of classical music but played maybe very slowly and with variations
