"Ordaigh" seems to be the verb generally used for order", so I'd say "Beidh mé ag ordú cinn..."
Breandan, are you sure about "ag iarraidh ar cheann"? I could go with "ag iarraidh cinn oraibh"
I was sure until I rechecked it.

De Bhaldraithe has
ordaím and
iarraim in the commercial sense of "to order" but I ran
iarraim together with the
focal a chur ar chulaith éadaigh on the next line and ended up with a mixed up idiom.
Ordóigh mé was my first thought anyway (but it felt like _that_ was Béarlachas.)
Incorporating Lughaidh's simplification of the first part:
Singular:
Go raibh maith agat as ucht do chúnaimh. Ordóidh mé ceann go luath.If plural
Go raibh maith agaibh as ucht bhur† gcúnaimh. Ordóidh mé ceann go luath.Unless I've missed something.
†Bhur is just pronounced a in Connemara).
