Graphic Design Job - Blackheath, WC, 7580

I require artwork for printing on t-shirts. The design can be an illustration of two teams/people playing a game of laser tag. It must have the team name incorporated into the artwork. Designs need to completed this week as I require 5 working days for the printing of the t-shirts. I have an design idea to inspire your creation or get you started. Please advise what it will cost to create two designs? Why 2? There are two teams and each team needs their own t-shirt design. And can you complete it this week? Please email me a quote and your completion timeline.
