I did complete the quest and have free pet slots, but unfortunately to morph an existing pet you'd have to transfer it to me and I'd have to transfer it back, and each pet can only be transferred every thirty days. I guess you could use the pound, but that's of course riskier because someone else could adopt it and I don't know if putting a Bhakoru in the pound changes its species or not. If you hadn't created the pet already you could have given me the name so I could create it as a Bhakoru and send it to you, which would have been much easier. As it is you'll need to use the pound (risky), find someone willing to morph it and keep it for thirty days to transfer it back to you (might be difficult), or get a Nostalgic Bhakoru Toy/Essence of Melody to transform it into a Bhakoru yourself (costs 10mil+). I could do the pound if you're willing to risk it, but if you go that route we should take it to smail (or even Skype since it's more instantaneous) so no one else knows what time it's going into the pound to snipe it. Otherwise I'm afraid you'll have to find someone else or get the items to morph it yourself. Sorry about that. :( EDIT: I thought I should clarify. You would use the pound to give the pet to someone else (me or whoever else volunteers), and they would morph it and transfer it back. Since it was transferred through the pound the first time, you would not have to wait thirty days to have it gifted back to you and since the Bhakoru would be transferring through giving a gift to a friend, that would bypass the species change of putting a Bhakoru into the pound (If that's even a thing; I'm not 100% sure on that). I would still personally recommend finding someone you can trust that's willing to hold it for thirty days or using the items yourself though just to be 100% safe.

Just so you don't get into trouble, you cannot pay people to make/change pets for you! They just have to do it for you for free.

I know the feeling! I often feel like doing things like that. But with pets, you really don't wanna even chance it! xD Gl getting your bhakoru!

It's good to hear that you already have an Essence of Melody. That's most of the cost right there. If you decide to go that route, be sure to make the toy yourself. It's over 3mil in user shops, but I just took the instructions to Vanya and made one for myself for under 200k. :) It had occurred to me that you might technically not be allowed to pay someone for a pet, but I hadn't noticed that part of your post until after I had already edited my own post twice and I was afraid it might be pinging you with each edit so I figured I'd bring it up in my next post instead of possibly bothering you again for that. xD
