Your best bet will either be a larger yorkie, which are still WAY small, or a rescue. My parents and grandparents both got their yorkies for $350. They are 12lbs and 10lbs but are still small enough to take EVERYWHERE. But, the good thing about them is that you don't have to worry about hypoglocemia, them getting stepped on, ect. ect. My parents are looking to getting a 2nd yorkie to add to their furfamily, but they are specifically looking for one larger than the standard (over 7 lbs). My dad spends a lot of time with their yorkie, and he just prefers the bigger ones because they aren't so delicate.
A lot of times with tinies you run into health issues. Also, they are quite prone to hypoglocemia which has been known to cause quite a few deaths in the little ones.
