This is a very generic question not really suited to the Q&A forum. We can help with specific questions and certainly if someone is feeling extremely generous or has a lot of time on their hands they can help but this is too broad for the forum in general.
You should probably start with the Beginner's Guide to SEO and let us know specifically how we can help. Also, depending on your current knowledge you may want to find someone to hire who can give you a jumpstart toward your marketing goals while you catch up on the basics.
I don't want to spend a lot of time on a generic question but just as a starting point, your homepage title is super spammy and needs to be changed. It also looks like you've purchased links in the past or had an SEO company who treated your site very badly.
Good luck!
