Valuation methods depend on the purpose of the valuation and any third parties affected by the valuation. It is more of an art than a science. You can start with a company CPA, and you can also get a business valuation expert involved. Unfortunately, you don't have an agreement about how the valuation is to be made for any purpose, so there will have to be a lot of dialogue and negotiation and compromise. But first, try to determine the specific purpose for the valuation. Remember that if you are basing your ownership interest as 1/3d of the LLC, you are valuing the LLC and then you interest is valued at 1/3d of that. The fact that you have extra sweat equity would not change your valuation, unless you were able to change your 1/3d ownership interest. Extra value can be distributed to you on agreement of all owners for any services or added value your provide in the form of a priority distribution or bonus, etc.
