Selling LLC with accounts

Hi,
I want to valuate my business to sell my LLC based in Delaware, I started it to act as an investment manager for a hedge fund. It is taxed as a C-Corp. And was formed in March 2017. It has a brokerage account with TD Ameritrade with full margin and options privilege. It also has some domains and a good virtual address. it dosen't have any revenues, just my personal trades.
What should be it's valuation, and if some one wants to be an equity partner how should the LLC be valued?

I really want suggestions, help maybe?

Thanks
