Hey guys i have 3 members in my in house team however i am looking to hire a few VAs as well. However i am almost zero at hiring VAs so would love to ask where i can find best VAs from (mostly design stuff ) and how much should i pay ? or how much you pay to your VAs . ...

I pay per week a fixed rate in the local currency. I then pay out bonuses with their invoices as I deem appropriate.
Seeing that you want them for design, I would suggest a quota-based output, and perhaps a list of angles / guidelines. Probably wouldn't hurt to share with them data on the banners that converted well so they can try and guess what elements are working.
I'm no expert at this but I've found 2 great Russian programmers over the last 12 months on Odesk.
I start with small tasks and scale up the amount of tasks.

Do they have friends?
Try hiring some Polish developers. Great quality, peanut prices.
I've been working with adminbetter.com for a year now, these guys are awesome. Please tell Nadeem that Sam sent you 
Onlinejobs.ph is great for long term workers. Odesk is great mainly for 1 time projects and sometimes long-term workers also.
You will get generally more loyal/long-term workers from Onlinejobs.ph though. I am in the middle of hiring someone from there right now and it is going great.
I pay $3-$5/hour for someone who is good in both HTML/CSS and Photoshop.
My company offers hq vas in house in our offices here in serbia. Pm for more info.
OnlineJobs.ph or EasyOutsource.com.
For a more detailed presentation on outsourcing check my speech in Bangkok, both the video and slides are on the forums.
Another vote for the Philippines. I've found my long term VAs through VA firms but it's all the same. Pinoys are loyal, smart, and have an excellent command of the English language.
