oscommerce template installation + few addons

WHAT I HAVE: 1. Al already have a domain and hosting space on hostmonster. 2. I will buy Templatemonster's template nr. 14773 for oscommerce. WHAT I NEED: 1. I need someone to install the latest oscommerce (I think it's oscommerce-2.2rc2a) and integrate that template into it 2. there are few extra plugins/languages which needs to be inserted in oscommerce: - SEO links, - Slovenian, Croatian and Serbian languages, - affiliate marketing - IVA tax for European companies 3. There is a need to allow customers to pay either by paypal either by invoice in advance (before the goods are shipped).
