Commercial Real Estate Attorney Needed

As if we needed more stress, we are seeking an attorney to advise us in an issue with our landlord (commercial property) - we have been paying rent on time for over 20 years including all through the pandemic, they are elderly and being taken advantage of by a 'handyman' who has proceeded to hassle us and has stirred up all this trouble. We believe we are well within our rights but need an expert on commercial leases to guide us through, and advise us on how to proceed.
