Somebody gave you the SHIP connection (State Health Insurance Program) - they maybe fine or they may not be - Sometimes these are volunteers that don’t know all that much - other times they may be retired Medicare insurance brokers or agents just doing some volunteer work.
You should not be frightened of independent Medicare Insurance brokers or agents. Pick one that has been in business in your local area for a long time. One that writes for a lot of different companies rather than one that is “captive” - meaning they just write for one company.
Many of them write for MediGAP policies, Part D Prescription Drug as well as Medicare Advantage which has a built in Prescription Drug plan.
You should at least read your book “Medicare and You” just so that you aren’t starting blind.
