Dazza, if you have windows live essentials, then you should have windows movie maker as well. Just type windows movie maker, or just movie maker into your windows search box, and hopefully its there. Its very easy to use, and you can link your 10 minute videos in that, to make 1 long video that you can then load up to youtube. It wont cost a cent.
