Integrating VEND Lightspeed with Klaviyo

Hi there

I have two clients who are having great difficulty integrating VEND Lightspeed and Klaviyo. 

Here’s what they have tried:

Client One:

• spoken with Lightspeed and they’re not planning on creating an integration any time soon for Lightspeed X-Series. 
• Tried using Storetasker to no avail
• Spoke to my local web dev who thought he’d be able to do something through Zapier - he couldn’t. 
• Put something on UpWork and only one guy got back to me, with a three week and US$1500 (approx) quote. 
   

Client Two:

My only work around… and note its messy… is this:

Vend - Link to mail chimp (free account) - then to Zapier - into Klaviyo.

Although it works, a straight integration would be nice. 

Does anyone have any suggestions or recommendations of developers who can create a straight integration from Vend to Klaviyo?
