Lawyer

Setting up your business is usually pretty straight forward so no particular speciality lawyer is required. You may want to work with someone familiar with all aspects of business though since businesses are structured to protecty you from liability and consider income tax issues. The attorney may refer you to an accountant to deal with the tax situation.

You may choose a lawyer or an accountant. I would suggest a CPA and they will know better what the tax implications of certain LLC's, Corporations, or other business would be.

To find a good CPA or Lawyer I would contact or go to your local REIC (real estate investment club) and ask around. You will often find that many investors will use the same or similar professions to help them because they will help you get the best set ups and deductions for yourself and your business.

Also, if certain CPAs or lawyers do not work for you can always ask for a referral from them. I have done this and gotten great contacts.
