Hi @stevelath
Firstly, no need to apologise - we’ll try our best to help!
The 3 jobs you mention - are you paid as an employee or as a self employed person? If the answer is self employed, then I believe QuickFile would be useful to you.
I won’t answer as to whether or not QuickFile is the right way to go (I’m biased ;)). There are other users on the forum I’m sure would be more than happy to give you their feedback on our software and it’s ease of use. But for you to understand how easy it can be to create things such as income, expense records etc., there are a wide range of articles in our knowledgebase which will show you how they can be done.
What I would recommend is signing up to QuickFile as it’s free until you hit 1000 ledger entries (and even then only £45+VAT a year). If you don’t like it, you can close your account and delete your data. If you love it, then that’s brilliant! 
What’s even better, we have features such as project tagging which would allow you to tag specific invoices and expenses to each ‘job’ (one for acting, one for driving etc), so you could even see how profitable one is compared to the other.
I hope that helps, but if you have further questions, please don’t hesitate to ask away! We have a forum used by the staff (myself and colleagues), accountants and other users
[Edit]
There’s a full list of all our features here. If you ever find that there’s something that should be on QuickFile but isn’t, we actively monitor the forums for suggestions, and if there’s a demand for them then we are happy to investigate them
