Need Suggestions about Clippers

So My boyfriend and I have been given a dog this past weekend that has terrible, terrible mats on his rear and I think he needs to be shaved down well his bottom.

The mats are really bad, and most of the groomers i've been to have been charging $100+ for it..

Im hoping my boyfriend and I can do this ourselves, since it's just his rear (but it's pretty heavy, i don't know how it got like that).

I have a budget of $60 and was wondering if any of you had some recommendations on what kind of Clippers would be good for this type of Heavy duty job. He is a mix, im not sure of what, his hair is curly and he has a cottony type coat.

any input would be nice and appreciated

I picked up some clippers (Andis) at Petco for about $36, it's an entire kit. Not great for professional work, but for shaving its pretty good. I had a dog come in that was SERIOUSLY matted down to the skin all over it's body...and these clippers took them off all in one piece VERY quickly. I would try that

Andis would be a good choice. They won't last you long, but should do this job for you.
