Dodge Journey Crossroad for 3D printing

I'm looking for a Dodge Journey Crossroad 3d Model for my collection, and I'm not sure what to do. The thing is, I found this model only here: https://3dmodels.org/3d-models/dodge...rossroad-2014/ The cost of a print ready version of the model is IMO too high. But I can't prepare the model for printing myself. Do you think it makes sense to order this service on their website, or is it not so difficult to do it myself? Or are there specialists who are ready to do it cheaper? If you can advise me where I can get this model in STL format ready for 3D printing, I would be grateful.
