Mechanic Job in Winchester, Virginia

In need of help with a 2011 ford escape limited v6 flex fuel. The heater core needs replaced or flushed. We cant take to a dealership as the quoted price is beyond what we can afford. The car over heats and no heat is produced inside the car. We have had to replce the water pump and serpentine belt as the pump seized and broke the belt. This was just the start of the entire cooling system having to be replaced part by part. We have replaced the thermostat, the cylinder head temperature sensor. We have flushed the radiator/cooling system and the mechanic shop didn't have the compressor to flush the heater itself to check if theres a blockage or not. We have already purchased the heater core incase it needs to be replaced but if someone could use an air compressor.and try to see if a blockage that would be wonderful. We have 2 young sons ages 9months and 4yrs old and are strapped at the moment. Hoping a mechanic will take payments at this point as we need this vehcile up and running asap to avoid using public transit with this virus going around to get our kids to drs appointments. We are at our wits end as this vehicle broke down after oening only 36hrs and has been broke down since 2/28 and nothing has helped so far.
