IT degree with A levels & 7 years of work experience

[Sherwood]

All international transcripts will only be accepted if the student provides them through an evaluation service.
The evaluation agency must be a member of NACES or AICE.

Does anyone know how difficult or expensive it is? I once looked at WAS and they wanted some kind of signed electronic version of the transcript, which could be hard to get.

English proficiency requirements:
IELTS - 6.0+
TOEFL - 197 computer based, 530 paper-based, 71 internet-based
SAT - verbal 550+
ACT - 24+

I took an IELTS test back in 2009 and my scores were:
Listening: 7.0
Reading: 8.5 (should I mention that I like to read?)
Writing: 6.0 (sadly, I don't know any grammar rules in English, literally)
Speaking: 7.0
Overall: 7.0

It's only valid for 2 years though.

Does anyone know which test would be cheaper, faster, and easier?
The prices I found from doing some research were: 
IELTS - 200$
TOEFL - 220$
SAT - 110$
ACT - 68$

I haven't heard much about the SAT or ACT; are they really common in the US?
