Four tanalised 8ft fenceposts at least 80mm dia or square - from £10 each. Trellis could cost anything from £20 to £60 per panel, depending on quality and how 'see-through' it is. As someone said above, if it's a windy site you would go for thicker posts and less dense panelling. Add £20 for screws and fixing brackets. £20 for enough concreting materials to set the posts in. Labour to dig four holes 2ft deep, set the posts in concrete and fix the panels, and to fetch the materials onto site and clean up afterwards. Add a bit for overheads for coming to quote for the job.
I'd say a summer day's work for one man - what that would cost may to some extent depend where you live.
Ask your quoters where you can see examples of their work. Word of mouth is a good recommendation. Remember, you only want to do this job once, so you need someone who can make it look good and do a solid job. Make sure they're insured for third party risks, covering damage to property and to people, not to mention services (gas, water, electricity...do you know where these, and drains, are?) - if they're evasive about insurance tell them to sling their hook. Get fixed-price quotes in writing; it's up to them to satisfy themselves they've identified all the snags, but be honest about any possible problems - for instance if you've buried a lot of concrete or tree stumps on the site, or if you know there are drains, etc. they're entitled to be told.
I'm sure I've missed things, but good luck,
