ERC 20 Token Raffle built into a website. Simple project.

I would like to build a raffle into our company website. The raffle is simple and has basic rules:

Front End:
1) To enter the raffle, members must purchase 1 ticket. 1 Ticket is equal to one entry. There is no limit to how many tickets one can purchase and no limit to how many entries.
2) To purchase a ticket, we require you to enter metamask and purchase with your LDV tokens.
3) We sell LDV tokens for customers to purchase.
4) The member can participate in more than one raffle.
5) Each purchase of a raffle is given a special number as a receipt.
6) Raffle status will appear under "Participating Raffles" which will display a status of: "Active", "Loser" or "Winner". Start date, End Date, Winner

Back End:
1) Tokens are available for purchase at $.05 per token. ERC Token (LDV)
2) Each Raffle Ticket Costs $1USD or 20 LDV tokens.
3) We sell our tokens in packages of 100 Tokens for $5, 440 Tokens for $20, 1200 Tokens for $50, 2500 Tokens for $100.
4) The Raffle should be able to scale and handle up to thousands of raffles per day. (Even though we are only doing about 5 raffles per day to start.
