I'm sorry, but I don't believe trainer can put a SOLID foundation in just a month. I'm not talking about BREAKING TO RIDE here. Usually horse needs lots of ground work before that, and it's not coming in one week. Some horses pick up fast, some slow, but if something missed there it may end up being a problem in future. For ground training it's better to get trainer to come, supervise, and give advices, because lots of it can be done by owner himself on daily basis. For breaking to ride yes, good breaking trainer is just perfect. Of course, if you have money to keep horse in training, say 90 days, that's another story.
