I am not sure who to ask or where to go with this, but if this is the wrong place, please tell me where to go (politely please ) OR better yet, if you know of someone who can do this for me on my web site, please refer me to them or them to me. I am happy to pay someone to accomplish what I need.

I need to create a formula to decide how much it will cost my customers to display my painted logos/signs on company car doors (for example). There are several criteria and each one depends on other criteria. It gets complicated and is beyond my grade 12 math skills of many years ago so I need some help. I also need to change this into computer code so that the client can calculate their cost online in real time depending on the criteria they enter.

There is an UN-CALCULATED BASE RATE (let's say $0.25 per mile), but this will need to be adjusted from time to time. The CALCULATED BASE RATE will depend on the following:

1) Type of route on which the art work travels.

a) Urban (higher cost per mile — base rate x 1.5)

b) Rural (lower cost per mile — base rate x 0.

c) Freeway (lowest cost per mile — base rate x .6)

d) Mix (determined by the percentage mix of all of the above

= CALCULATED BASE RATE 1

2) The length of time when the artwork is being displayed during specific times of the day

a) rush hour travel (7 AM – 10 AM and 4 PM – 7PM) will cost more per mile = base rate x 2

b) Daylight hours other than rush hours = base rate x 1.5

c) Night hours other than rush hours = base rate x 1

1) x 2) = CALCULATED BASE RATE 2 (not sure if this should be 'X" or "+" )

3) The distance the artwork travels.

distance x above CALCULATED BASE RATE 2

So, for example if a client's sign travels 100 miles (10 miles urban, 30 miles rural, 60 miles freeway) for 7 hours (3 rush hours, 3 daylight hours and 1 night hour) what will the rate per mile be? How much will it cost in total?

Please feel free to ask any questions or comments. Thank you for your help in advance.
