Ebay, amazon or whatever the local "buy things from the internet" place is. You can find a telescope for under $100 at each of those places. They will be low quality but usable. Building a telescope is difficult, takes time and for the size you want it's cheaper to buy one. Once you've bought a $100 scope and discoved its limitations, then you can sell it, use the money to buy a good mount and build your second scope :)

Do you have to make it? You can buy one for about $30. Course the optics aren't going to be all that great but it will work.

Now Vivitar does make vary cheap products both in cost and quality.
Here is another option that should be a lot better than the vivtar but still not all that great.

But if you want good quality you want a refractive scope.
