Before you shell out $15k-$75k be aware that Google's record of maintaining API's is very bad. They very aggressively deprecate API's with little or no warning

Before you shell out $15k-$75k be aware that Google's record of maintaining API's is very bad. They very aggressively deprecate API's with little or no warning and provide zero alternatives. In my opinion, they have very little concern or respect for people developing on their various platforms. Maybe it's not applicable here but I've been burned by them before because of this.
