Design a set of 16 icons for ski rental website

We are an independent ski rental company and have recently updated our online booking system at [login to view URL] using a 'Flat UI' design scheme. When clients make a reservation, they choose between 16 different categories of equipment (further details below) each of which is represented on the site by a small icon. It is these icons that we would like to update and are looking for a graphic designer to help us make this possible. The icons should be stylistically consistent with one another but convey in as simple a way as possible the type of rental or service package that it relates to. The colour palate used on the site is quite limited and so we suggest the icons are produced using consistent colouring (basically grey, black and green). The categories of equipment / service are as follows: 1. Adult Bronze Skis - skis for complete beginners 2. Adult Silver Skis - skis for intermediate skiers 3. Adult Gold Skis - skis for advanced skiers 4. Adult Platinum Skis - skis for expert skiers 5. Adult Touring Skis - skis with specialist bindings which allows the skier to walk uphill as well as ski downhill. (you can just google "Ski Touring" if you're not familiar with ski touring!) 6. Child Skis - skis for kids aged 3-6 years 7. Junior Skis - skis for kids aged 7-12 years 8. Teen Skis - skis for kids aged 13-16 years 9. Adult Beginner to Intermediate Snowboard 10. Adult Intermediate to Advanced Snowboard 11. Junior Snowboard (7-12yrs) 12. Teen Snowboard (13-16yrs) 13. Ski tune/service - edge & wax only 14. Ski tune/service - full service 15. Snowboard tune/service - edge & wax only 16. Snowboard tune/service - full service The existing icons have been attached here just for reference although are not necessarily intended to be used as a basis or starting point for the new icons. The final icons should be provided in psd format so that they can be manipulated if necessary and saved to png format for use on the website. We may also like to use the same icons in printed materials / booking forms so they must be provided to us for use without limitations. The successful applicant must have experience of icon design (links to previous work would be gratefully appreciated). Further details or clarification of the details of the project will happily be provided on request.
