Sounds like a nice new venture mate, there's nothing of that up the Exeter way apart from Bridge & SP, there's an empty unit down here that used to do car audio that has now had to close, I used to do odd jobs for him in my spare time.
I'm self-employed at the moment, & earnt enough in the last 2 months for me to take a complete break in December & plan on starting some more in the middle of January.
The website looks pretty nice, but I'd recommend getting your own space as soon as you have the funds.
If you need any help with logos & stuff feel free to give me a shout.
I can also give you a super deal on advertising if you want, if you do go down the car route, I'm helping to run a car club with around 250 members at the moment
Hope all goes well
