This is my first post here, so apologies if I made any mistakes.
Also, really sorry for such a lengthy first post. I really have quite a lot on my mind.

Summary and main purpose of this post: How do I find/pick schools that are easier to get in (For a Masters program)?
My details:
Undergrad Institution: Foreign
Major(s): Electrical and Electronics Engineering
Minor(s): n/a
GPA: ~3.2-3.5/4.0 (Not sure how it converts. My university only gives honor classifications: 1st class, 2nd upper, 2nd lower etc. I had 2nd upper)
Type of Student: International student
Due to personal issues (mainly monetary problems to keep myself alive), I was unable to concentrate and get the best grades.
Now that I have worked a few years, I am doing fine financially and actively looking for a chance to study Mathematics.
Eventually, I hope to be doing Graph Theory related stuff.
(I picked EEE initially as I desperately need a job after I graduate. I was not certain if Mathematics would get me one for sure.)
Unfortunately, now I find it difficult to even get started.
Not only are my grades not outstanding, I have a mismatching major to boot.
I know for sure that I will not be admitted into good/decent schools.
Hence, I am hoping to enroll in a Masters course in some schools that are much easier to get in.
However, I am not sure how to find them.
The only good things I have going for me are the following:
1) Strong recommendation letters from my current employers
2) Good job records and some rather rich experience to write about
3) Very strong/experienced in programming
4) A Mathematics job: I was doing Signal Analysis originally and now doing Cryptography
Unfortunately, I will not be able to get strong letters from my undergraduate university.
In fact I do not have contact with any of my professors anymore.
I had just taken my GRE and expecting it to be around average. (Perhaps some 60-80%)
Actually, it need not even be a Masters program.
I am also considering all sorts of options that will give me a chance to get started on having experience in pure Mathematics,
up till a point where I will get a good chance of getting into a decent Masters/PhD course.
Except, I cannot think of any outside of redoing a Major in Mathematics altogether. (Which will take too much time.)
It suffice to say that I really want to get started soon.

I would be really grateful if anyone can give me any advice regarding this.
Thank you if you even bothered to read the whole lengthy post!
