Putting a gate into an existing timber fence

Hi, I have a 5m fence line with existing posts which I would like to have a gate added to, between the first and second post - see third photo for rough idea. Want this done so I can access backyard with wheelbarrow and tools easily, as other entrance is on other side of property. Open to recommendations on type of gate to install depending on strength, ease of job to be done and cost.
