Lead Generation for Accounting and project management firm

I need a lead generator who can help generate leads for different categories of services around finance and accounting, the ideal market is UK, Europe, US, UAE and GCC Region, Africa. We provide accountancy and advisory services for SMEs, medium sized businesses and large corporates.
The ideal person will be proactive and have a plan of how to ensure they generate at least 20 solid leads per month with help and support from me where required. Leads NOT Prospects. By leads I mean, contact would have been made and there is an interest expressed or genuine inquiry by the prospect, that is a lead. We will trial the ideal candidate for 3 months and if all goes well and you can deliver, this will be extended and renewed every 12 months.
