It's actually pretty easy and the difference in cost between LLC and C-Corp isn't substantial (if you use Gust Launch it's all included in the $199-$239 monthly) but either way, since the double-taxation mostly doesn’t apply to high-growth businesses that reinvest capital instead of paying it out, there isn’t actually much difference in tax burden, and what there is is significantly outweighed by cost of converting to a C-Corp later.
