I agree with Glenn there. Most 'point and shoot' cameras focus at a minimum of between two and four feet. Check the camera instruction manual for this, to see what the minimum distance is. If the camera doesn't have a macro facility, then shoot from just outside the minimum distance. For example, if it's, say, two feet, then shoot at around two feet six inches, using a plain, uncluttered, neutral coloured background - paper, card, cloth sheet etc.
You won't get the same resolution or close-up detail as would be expected from macro, but you can then crop the required area, and re-size that to the best you can get, with an overall size no more than 800 x 600 pxl.
