Welcome to the forum
We have
in consideration of sth:

in consideration of your many years of service, we are pleased to present you with this gold watch.
in consideration of your efforts here is a check for 3000$.
  Examples From The Great Oxford Dictionary: "1540 Act 32 Hen. VIII, c. 42 Wherefore, in consideration of the premisses, be it enacted, etc.    1653 H. Cogan tr. Pinto's Trav. lxxvi. 310 Who in consideration of ten duckets that we gave them, fell to diving into the sea.    1818 Jas. Mill Brit. India II. iv. ix. 286 In consideration of this benefit they should pay into the exchequer 400,000 l. every year.    1875 Jevons Money (1878) 119."

In the interest (interests) of someone or sth
As an advantage or benefit to someone or sth; in order to advance or improve someone or sth:

I don't know what 'at a consideration of' means! in fact I'm not sure whether it is correct.
