What ways could you suggest I improve?

Like everyone else I'm looking into improving my earnings. Currently I'm doing three different things as I work 6 days per week over 3 shift pattern

eBay
Usual stuff, just selling, sometimes loads, somethings nothing for ages. So I've just excluded this one since the listing fees are killers. Although if I went full time I was contemplating using a royal mail yearly postage service (sat collection)

Youtube
I run ads on my youtube accounts and generate revenue this way, it's slow going but my earnings are increasing more and more each month so I'm focussing on this one and delivering more specific content as I think because of the audience it's got better potential

I've started doing this more now, it's hard to write reviews at times, so sometimes I get around 5-6c per song, but usually it's around 15-20c per song. I'm doing a minimum of 10 songs per day which works out around $40 per month for me

Now, I've tried things like Toluna/Clixsense, but they never seemed to work for me, so not sure if I was targeting them right or they're slow earners (what sites could people recommend)

The things, I'm looking into taking up to increase my earning are...

Typing - I can average around 80wpm normal speed, so possibly doing transcription work (if I can actually figure out what it is) and audio typing aswell as typing up manually written paper into bookform. I've tried peopleperhr, but it seems to be mainly flooded with people wanting you to fill in generic Captcha systems or abusing your eBay account for mass selling with wholesale. I'd like to look into wholesale but I'm not risking my own eBay account, I'd rather setup a seperate one

Youtube - Obviously I've already got a small presence, could anyone suggest ways in improving this

Website - I have my own webspace, so can run adverts / affiliate stuff on there for more potential

Thanks for reading. My current salary is 21.5k per annum, but I make around 25-26k after overtime. I'm looking at making 35k by ways of the above 3 if possible or further

I'm prepared to work long hours (as long as home based) and dedicated to doing it, but I'm stuck on how to maximise my potential earnings. Could anyone suggest tips on improving my eBay ads, earnings, etc?
