I have two questions related to LLC to S Corp conversion:

1.) What is the price range for providing such service? which include at least of filing form 2553, bookkeeping setup, payroll setup, apply for an EIN, and ect.

2.) If the taxpayer has two incomes at the same time: W2 income and a business income on Sch C.

If his W2 income is about 160K and his LLC income is about 100K. Under such situation, whether it is necessary for him to consider conversion from LLC to S corp? With 160K w2 income, he already pays the maximum self-employment tax.
