Now your just showing off
Naw...thats just the small stuff
Try a whole floor of fixtures and showcases at Macys. Especially an ELIPSE shaped showcase line

THATS showing off.
i was thinking i could probably do a better job myself.. rent a circular saw for the day (£15 a day) and just go for it.
Possably..if he were a REALLY bad craftsman. Depends on how good you are with a skill saw too.

Personally, if I had only one tool, it would be a router/table. Of course, you need a shitload of carbide bits to go with it too. And about ten years of experience as well.
Have you ever worked with MDF? Have you ever tried to cut a panel thats SQUARE? Not as easy as you think, especially with a skill saw. Remember, out of square panels make for poor assembly. But like you said. Go for it. Experience is the best teacher.

Heres a tip though. If paint is your finish of choice, MDF is the substraight to use. For trim pieces, or edgework, use Poplar. Takes paint real good. But ALWAYS prime the surfaces before painting. And thats another thing. Lacquer is usually the finish of choice for woodworkers. If you can't spray lacquer, use a good enamel and brush. But for gods sake, don't use latex. It looks like crap for fixture work.
why not cover with a laminate surface?

Hmmmm, if he has to rent a skill saw, I doubt that laminates would be a good choice. Ever tried to trim laminate after its contact cemented in place, without a router? No fun.
