Ill pay $ – Need help with custom fields

Hopefully I dont lose anybody when I try and explain what I need to do.

First of all, Whoever gets this working for me will GET MONEY VIA PAYPAL if wanted. Not much, but Id be willing to give like $10. If you can solve this you can probably help me with a couple other things I need, so theres the possibility of even more money.

For each post, I need to display 2 images side by side at the end of the post. Call them Image Spot 1 and 2.
I dont care how theyre stored but for each image displayed it has a unique url its linked to. So say I have 10 images. Each image links to a certain url. I need to be able to type in the name of the image in the custom field when making a post and it put the image in the post and link it to where I previously defined.

If you dont understand what I mean, I can explain it further.
