Trading with the Sidewinder is slow but not impossible, and if you're having initial difficulties it's a good way to learn your ship, practice docking, and get some confidence with flying.
Pick up 2 containers of liquor from Azeban City and take it to Freeport. If you get interdicted put all power to engines, hit C to restart the frameshift, and tap boost to keep away from the pirates. You can outrun anyone. At Freeport sell the hooch and buy some Rutile, take it to Dahan. There sell the Rutile and buy some Aluminium to sell at Chango. At Chango buy mineral extractors to take to Freeport. Once you've done that you should just about have enough to buy a second fixed pulse laser, which makes combat easier. This shouldn't take much more than an hour even with a saturated market.
