How much is a tour guide if we hire from Travel China Guide?

TravelChinaGuide does not have this kind of service of providing us a English speaking tour guide only for visiting any of the tourist attractions in Beijing. Last month, I also want to hire a tour guide for visiting the Summer Palace, but they did not provide it for me. As a result, I choose a journey from these routes: https://www.travelchinaguide.com/package/beijing-one-day-tours.htm, which is very good. They are kind and the service is very good, too.
