Need an experienced "PayPal developer" ??

I actually need to know first if this can be done.

I currently have Buy It Now buttons for my bookmarks, which you can see throughout my site (just View Source on any of the pages that have a PayPal Buy It Now form on it). I don't "think" I need "shopping carts" or Add to Cart buttons.

What I DO need, if it can be done, is to allow the customers to enter their own quantity of at least 10 and have the code calculate the price each depending on how many they order.

So for instance, if they order from 10-25, the bookmarks are $1.95 each; 26-50, $1.75 each, and so on - on the concept of "the more you buy, the less cheaper they are."

For example, can this section of the code be rewritten to accommodate the above:

<tr><td><input type="hidden" name="on0" value="Price">Price per Set</td></tr><tr><td><select name="os0">
<option value="Set of 10">Set of 10 $15.00</option>
<option value="Set of 25">Set of 25 $37.50</option>
<option value="Set of 50">Set of 50 $62.50</option>
<option value="Set of 75">Set of 75 $90.00</option>
<option value="Set of 100">Set of 100 $115.00</option>
<option value="Set of 125">Set of 125 $137.50</option>
<option value="Set of 150">Set of 150 $150.00</option>
<option value="Set of 175">Set of 175 $166.25</option>
<option value="Set of 200">Set of 200 $180.00</option>
</select> </td></tr>

I've seen PayPal's code variables but I'm clueless as to how to build them into the current Buy It Now codes. :confused:

The way I have things set up now is pretty easy for most of my customers unless/until they need different quantities other than sets I have listed above. In fact, for my last three orders I actually took the orders over the phone, provided a quote and invoiced them through PayPal, whereas they could have easily just ordered online if the order forms were set up properly.

Would someone be able to help me with this? And if so, would you provide a quote to do this?

Thanks very much!!
