Nothing prevents the LLC from entering the contract with you or your being compensated with a percentage of something (sales, profits, etc.)
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

This is not complicated. It is a Contract - pure and simple. Have a Business Attorney draft the contract. You can easily find one on Avvo.Com under Find-A-Lawyer. Good Luck!
Nothing complicated or especially unusual about this sort of arrangement. As Mr. Doland stated, an LLC may enter into agreements with independent contractors and generally structure compensation as the parties see fit.
An attorney in your area should be able to assist you in reducing the terms to writing. Best of luck.

I agree completely with my colleagues answering your question. I would just add a few things to think about (be concerned with) as you have someone draft your IC agreement: (i) you're going to have no control over what the company does to assure your continued income, except to the extent built into your agreement (e.g., LLC dissolves, with the only member starting a new company); (ii) relatedly, "profits" can be subject to substantial manipulation by the owner; and (iii)
your status as an "independent contractor" (versus "employee") may be a sensitive issue.
This response to your question is general in nature, and is not intended (and is not authorized to be received) as reliable legal advice upon which any action or decision can be based. Other facts and considerations not known may substantially affect the answer as it applies to your particular circumstances.
