Lay-by / Split Payments

I sell high value hand knotted Moroccan rugs, many of  which are currently beyond the financial means of most people.

 

I would like to be able to offer potential customers the opportunity to lay-by and pay off over a period of 3 months, with a 30% deposit.

 

I am about to set up a lay-buy extension on my website linked to Paypal. The results of a facebook survey I have just conducted revealed an overwhelming desire for this.  

 

Is there a split payment option on eBay Australia? If not, can anyone please advise me how to get around this issue?
