What will it cost to take huma to court

I have been quoted £1.260.00 as a start off fee but could end up costing as much as £6.636,51if solictor has to take huma right through the court process. Does anyone know if this seems a fair price.

We have been quoted 2000 euros however if we did take them to court, this would only be to claim back deposit and interest etc as we have full guarantees  this appears to be for the worst case scenario if the lawyers need to go to court to seize assets may differ depending on amount being claimed. 

We paid (upfront €1500) That is to pursue the refund, via the court,  €11000, this was our first stage payment , plus costs, and interest. We will see..................................

Proceedings started July this year.
