Optimize Mobile Sales Pages & Funnel

We own a few products that we sell via Internet Marketing. We use both display & search engine marketing to generate traffic to our product pages. We are currently launching a new product and want to optimize our mobile sales page along with sales funnel to help ensure optimal conversions and revenue. This would be a recurring job on a contract basis for someone who could help us deploy different versions of sales pages so we can split test accordingly Pages need to be optimized for mobile and load very fast (especially on 3g etc) Thank you!
