Implement a Joomla 2.5 Landing Page + Sports Predictions Component + new pdf invoice

General information for the website: We have a customized sport betting website
Kind of development: Customization of existing website
Num. of web pages/modules: 3
Description of every page/module: I have a custom Sport Betting website based on a Joomla 2.5 Customized Betting Component, the website was developed in 2014, the developer who worked in the project is currently unavailable and we need to add new features to the website ASAP as launch date approaches. The final site language will be Portuguese (pt_PT) so all field must be fully translatable using Joomla language files.
Description of requirements/features: So what we need is the following:

1. LANDING PAGE WITH REGISTRATION + LOGIN
The testing website is currently online, but we realized that the registration page is very complicated (lots of fields) and unattractive, not simplifying user engagement. We need someone to design and implement a Landing Page to integrate it into default template and database with registration form and login area.

2. SPORTS PREDICTIONS COMPONENT
Install the Sports Predictions 1.4.8.5 for Joomla 2.5, its module (frontend Modules), and customize its looks and feel to match version J 3.0 like in http://www.soccerpredictions.tips/demo-sports-predictions.

3. SETUP A NEW PDF RECEIPT/INVOICE TEMPLATE
Currently the betting component support 3 types of betting, single, multiple and combined, each generating an invoice A4 (to be kept) on the backend and frontend. We want to implement a new small (80mm wide paper) receipt/invoice template for printing into thermal printers.
Specific technologies required: Advanced knowledge of PHP / MYSQL / JAVASCRIPT / CSS / JQUERY / Joomla CMS
