Personally, I would be shopping around with both online and physical shops that specialise in doing/printing this stuff as well for you...the costs are very inexpensive compared to what places used to charge...and have come down alot...dont buy the plotter/cutting machine cause cheap is cheap, and u get what u pay for...I have seen alot of people setting up shops over the last 15 yrs in security, and vinyl work supplied by companies who specialise in it has come down to peanuts...

Getting vehicles is very expensive, but getting fixed A style sandwich boards (no pun intended) and various corflute board style vinyl advertising stuff for takeaway shop merchandise/promo stuff can be very very cheap....last time I looked for a friend, 3 months back, it was very cheap. It wouldnt cost you anywhere near $700 to get enough stuff done up to last u a year or two and u can use it over n over again...

Even getting a large wall mounted menu style board set up is worth being quoted n done by a professional who does this style/type of stuff all day everyday and the results will be A class, versus not so great perhaps because the setting up/font style and layout is for reasonably talented people who do this stuff for a living and do it very well cause graphic arts is their passion/profession.
    What will take them 3 or 4 hours on the specialised software, might take u five times that...get various quotes thats all i am saying...the economy is extremely slow/stuffed, people are scratching for work and prices are way down. Plenty cheap places both in Brisy and the Gold Coast and all can take most enquiry via phone and the net with only a few day turn around and delivery...
