Chess coach advice for kid

We are looking for opinions on how to find a good chess coach for our 7 year old kid.

Here is the background information (I´m choosing to stay anonymous):

- Neither myself nor my spouse play chess at all.  

- Our child has only been playing chess for about 4-5 months and after a few fairly serious tournaments (Kid did way better than anyone expected) was invited to play at the U8 Nationals (we live in a european country).  We turned down the invitation because we decided that our kid was too young (they were only 6 at the time). 

- Subsequently we received a proposal to train with one of the top coaches (verified) in the country (I can´t name names).  The proposal included attending Europeans and World level next year. We declined because we just couldn´t afford THAT amount of money.

- Kid was tested by a licenced psychologist (at school it is standard here for bright kids to be tested by school psychologist) using a standard WISC-IV test and reached the ceiling (99.9%) of the test in almost all categories.  When not at the exact ceiling of the two other categories it was 98% and 99% .  For any IQ experts here, I´m taking these numbers directly from the psychologists report. This kid is more intelligent than we imagined, which is why I´m even seriously looking at options for training.  

- Currently we train with a local coach who is, in my opinion, amazing - he cares a lot about his students.  However, we are warned by unsaid top coach here that this guy won´t be able to bring Kid up to the top level. 

- Also I have been warned that the next three years are critical - is the window really that small?  

- Kid LOVES chess, and will happily train several hours a day. 

We definitely have no insight or idea how to move forward, if it´s even necessary to make any changes.

We don´t want to waste Kid´s talent, but we also don´t want to pay astronomical amounts of money. 

Any advice would be appreciated.  Thank you in advance. 

Look for coach credentials, feedback from parents and students. You can also search online coaches with affordable rates.

There are numerous good coaches out there. https://www.chess.com/coaches.

I am willing to take your son as one of my students and coach him,
