Hello :) This isn't a big job, I'd be more than happy to guide you through this. Don't worry about the confusing terminology! MP4 and MPEG4 are actually the same thing! Feel free to message me and I'll give you some free advice. You'll be converting videos yourself in 5 minutes.
If you like I'll upload a little video to YouTube showing you exactly how to do it. It's very easy and you won't need to pay for any software.
I am a British web designer experienced in HTML, PHP, MySQL and Server Management. I deliver all my projects on time and to the highest standards. You don't pay until you're happy. I am ready to work straight away. Please see my exam awards below to assure you of my ability. All questions are welcome and I'm always happy to give some free advice!
