I am an expert Magento developer. I can easily assist you with all your issues and help you to get your site live quickly. One except is the SEO. I can help you with SEO but I am willing to go only so far on the SEO. The reason i state this is that proper SEO work is in depth, time consuming, and ongoing. Individuals and companies who boast instant SEO as if it is as simple as running an algorithm on your site are either using lying or using blackhat SEO techniques which often backfire in the long run & can get you blacklisted by google. If you require additional SEO work my company has an SEO department that will assist you for an additional fee.
