What type of law firm specializes in all-inclusive estate services, like taking care of taxes, paying bills, sale of house & belongings, etc.?

While some law firms might take on those services, normally that sort of transactional detail will have the personal representative or executor (or trustee if that is how the assets are held) take the lead in gathering and liquidating the assets of an estate. However, the personal representative or executor will usually hire professionals to do the specific necessary services, such as an attorney to do the required court filings, an accountant to make the required tax filings and perhaps a real estate agent to help with the sale of real property. An alternative is to name an institutional personal representative or executor (such as a large bank with trust powers or even a private trust company) and they might be willing to handle that level of detail, although it is likely they will also hire ancillary professionals to help them do that.
