Need a person with a mathematics degree to validate/certify some calculations

I need a person who has a mathematics degree, and who can *prove* that they
have this degree (presumably by the university being willing to confirm the
degree by email - or by whatever other means of proof). I have written a
short paper. It involves eleven very very simple calculations. I need
a *qualified *person to check these eleven calculations, and then certify that they are
correct.

Here is a single example of the type of calculations involved:-
The Earth Year is 365.256 Earth days. Venus' rotation period is 243.0187
Earth days. During one Earth year, Venus rotates (365.256 divided by
243.0187) = 1.503 rotations, ie:- 1 complete rotation plus a *RESIDUAL
ANGLE* of (0.503 x 360) = 181.1 degrees. These are very very simple
calculations.
