I've dealt with him, first by recommending some work he was selling for my brother to buy. The work was well priced but my bro had a few cancellations and issues with other wc's which didnt bother our kid.
I spoke in depth to kapre and sent areas and postcodes of the areas I wanted canvassing but just before the campaign was due to start he insisted on up-front payments and wouldn't guarantee the new customers. I wasn't very happy at the advanced payment requset and asked him why, he simply replied "I've been ripped off before". I wasn't at all happy about this after I'd brokered the sale of one of his rounds and expected a more professional response.
Now this is Just my experience, If anyone has had good dealings with kapre please write them up as he may have happy customers.
Regards, Simon
