transferring interest into offers

I have a load of my players with a wanted sign next to them but have just gone through the Jan transfer window without any offers. I have not set high asking prices to warn away potential suitors and am doing reasonably well, 3rd season with Villa - 2nd in prem, lge cup final, first knockout round champs, fa cup 5th round. I am ideally looking to sell them at the end of the season to raise some finances as that has been my plan with villa, buy young sell after 2-3 yrs good service. I do not want to offer players out as this can make them upset with me.
