If you are in bangalore, you can contact Alphakennels (http://www.alphakennels.in/br eeds.html
) as I found the breed maltese in their website, you can also contact poddarkennel (http://poddarkennel.com/
) but there are some complaints about him while I browse about him.
As you said you need toy/lap dog, why not you consider Miniature Schnauzer (Very Very Intelligent & Cost around 30K for show quality) and Miniature Pinscher (Very Intelligent, King of Toy Breed & Cost around 10K if you get it in Yashbans, Bangalore). You can also consider Papilion. If you want to get Toy/Lap breed try to get breed which is intelligent so that it will be easy for you to train your dog and it listens you. This is just my opinion.
All the best
