If you want to see something hilarious, hit up some of the Power TV clone sites (StangTV, for example). Their version of a 'budget build' with cars begins somewhere around $25K....and up.
Most magazines are only out there as four-color paid advertisements....with an interesting bone or two thrown in as 'news'. Popular Hot Rodding is a hilarious example, in that they've only just now figured out that the peasants are becoming annoyed with their version of 'budget': The last, most glorious example of a 'budget build' was a big block Mustang that they got into the 9-second bracket...once again, for $25,000. They also regularly tout 'home-built cars', however, come to find out, these 'home shops' are fully-outfitted fabrication facilities in which tens, if not hundreds of thousands were spent to set up: Basically, it's a guy who either can't find a wife to save his life, or he's already doing race-car fabricating, and and built his 'backyard project' only as an advertising tool for his work.
If you're a shop attempting to get in more work, then be honest about it. If you're attempting to hide what you're doing so you don't have to pay a message board or magazine for advertising space...just like every other business has to do....sorry, but take it somewhere else.
There are a few scant offerings that dare to attempt to break out the mold, such as Motocross Action, and Grassroots Motorsports, but even then, it's almost impossible to get a 'budget' idea of how to do something done with a bike or a car, unless you happen to stumble across some options on a message board (like this one) somewhere.
