You're playing in a dangerous game, living in the US. Recommend going off shore yourself asap but, the type of corp that you want is called an IBC (International Business Corp.) Best to set it up in Belize (not too far from Texas) or Panama. Both protect your privacy.
If an off shore broker thinks that the corp. is owned by US citizens there is a strong chance that they will terminate their agreement with you. When you set up your corp, tell your lawyer that you want to keep your identity off the record and they will help you to accomplish that.
I have worked with Orion in Belize City, cost around $1500 to set it up and about $600 a year after the first. Good people and knowledgeable. Actually one of the lawyers there is speaker of the house or some high position in Belize.
When you set up your business, your lawyer will ask you how many shares you want to divide your business into. If you sell off a share, you are selling your business. Maybe better to ask the lawyer about selling investment bounds.
Hope this helps.
