Hello,
I can sort your store issues for you. My advice would be you move it to a dedicated VPS (they cost only about $15 per month) - but if you want to stay with hostgator that's fine also.
I will install SSL certificate for you, and fix the front page loading issues for you in internet explorer.
Also I can verify the HTML code is current with best practice.
I am in the UK so our timezones also match. Please see my profile to read some reviews, all of my clients have rated my work as 5*s.
I can start on this now, and have it finished by tomorrow morning.
Best,
Gary
