I'm sure there is a guide somewhere on the Delaware Division of Revenue state website. Tax law may be complicated but it's not a secret. Since you have no revenue I imagine that it won't be super complicated and that even if you make a mistake or two that no one will ever look at your return. (Maybe if you go public way down the line?) Paying someone may "only" cost a few hundred bucks since there's gonna be zeros all over the place and this is likely to be deductible from your next in Delaware.
