Speech is one of those skills that's easy to level early anyways (particularly if you already have the Nord or Breton head start). A trip to Riften can boost you many levels quickly- get a charity blessing and the Dibella blessing from Haelga's, and you'll be able to pass the persuasion tests for the Riften gate, Maul, the Black Briar guy, the Argonian woman, Sapphire, and the three higher level persuasion checks from Svana's mini mission (you'll need speech up to 50 with your blessings for those IIRC). There's three or four more persuasion tests up in Solitude as well (not to mention all of the other spots you can get one persuasion test easily). While you're in Solitude, you can go down to the docks and regularly get 12 salmon roes for the uber valuable roe potions. If you have the Thief Stone and Well Rested and you're selling things as well along the way, you can get to 50 without paying for it quite easily.
