Dispute resolution or go to court?

[Nasa89]

We have a case of professional negligence against the surveyor we used when we bought our house. We raised the issue with him and he has refused any liability. We got reports by another surveyor & by an expert witness engineer, both of them think that we have a case against our surveyor and should go to court (repair costs are in the region of 15k).
His firm’s complaint procedure says complaints can go to a dispute resolution organisation that solves issues through adjudication. I read their website and they are independent, legally binding, they provide with a resolution in less than 90 days & very important... free! We consulted a solicitor, who said to go to court and that their fees would be over a thousand. we are both working but have no savings after buying the house and furnish it :-(
Is the CEDR (dispute resolution company) any good? Do they really look after the costumer’s interests or are we better off going to a solicitor? It haS been 7 weeks already since we complained to the surveyor, he was giving us hope then he offered to settle for next to nothing claiming our report and quotes are very inflated. I don’t want to waste another 2 months writing letters, emails and submitting reports to find another wall (the house needs to be fixed sooner than later!). the cedr seems too good to be true & we have no idea about legal matters so it’s hard to know what to do! TIA

Anyone had any experiences with a dispute resolution centre?
