Don't give up, man. From what I can see in your post, you're doing Masuda Method right. I'm actually breeding for a shiny Beldum myself. The last time I bred for shinies, it didn't take long, but I think my luck has hit a wall for now. Well, here's hoping we both get our shinies soon.
Also, if you're playing X or Y, you can find Metang in a Steel safari, and a Frogadier in a Water safari. However, the Frogadier may not have the HA, and I don't think the odds are much better in the Friend safari, although I believe they are better. If you want more control over over the Pokemon's nature, IVs, and ability, I would stick with Masuda Method, but if you just want the shiny and someone has the appropriate friend safari, perhaps looking there is your best bet.
