In TX, it costs about $200 to set up an LLC. There are definite advantages over a SP but I'm not a lawyer, as they say. If you're comfortable reading up on everything yourself you can do it without a lawyer / CPA. Of course, their fees are tax deductible. The downside to an LLC (like the previous poster mentioned for S Corp is taxation). In TX, I think it is up to 4% of gross revenue but, IIRC, it's only for income from TX.

Speaking of lawyers, whatever happened to Ken (Verbalkint)?
