Why trust anyone to cut your hair? They almost always do it wrong. If you want something done right, do it yourself...
But do it like professionals do, don't try to scissor cut things short, it just doesn't end up looking good. You can get clippers for like $15 at discount stores, mirrors aren't all that expensive either.
If you are growing it out just let it grow! Just trim the split ends every 6 weeks or so. If you keep cutting it, you just prolong the already long process.
