Bring advertisers on website - high commission

We need a professional who brings paying advertisers (medical companies) on our medical website. ## Deliverables We run a website for radiology professionals that has meanwhile 10.000 members. We want to start offering advertisements/sponsorship which are targeted to our members. Basically advertisers would be any medical companies who are involved in the field of radiology (device manufacturer, software and service provider etc). We pay everybody who brings in a new advertiser $500 PLUS 30% of the advertisement value the advertiser signed for (total value must be over $3000). Advertisements start at $1000 for the smallest banners and up to $10.000 for the main advertisement sections. (We have many affiliated medical sites that could be enrolled too - which would be also attractive for the companies). We also offer bundle packages. Based on previous negative experiences when we paid upfront, we want to make sure that we don't pay into a money pit and will pay only AFTER the advertiser has paid us. It is up to you how much effort, time and resources you bring in to make the advertisers sign the contract - we will only pay for "delivery" - which is the fee from the advertiser. We have multiple advertisement/sponsor opportunities which need to be discussed after we established a level of confidence that you are the right person/company to do the job. We don't want SEO enhancement! You HAVE to CONTACT the companies directly, NEGOTIATE with them and CONVINCE them to get enrolled as our advertiser/sponsor. Thank you
