Advice on the value of my collection

[Fuzsybear]

Regrettably I am having to sell my collection of bikes. They were my father's and I was planning to get them back up and running as been sat in garage for a few years. Unfortunately I don't have time at moment. I have a Carlton Pro-am 12, a Bianchi Sprint and a Whyte prst4. The first two just need a little service to get roadworthy. The prst needs aa fair bit doing, shocks service, bearings, tyres, a bolt on one of the hope calipers has snapped and some general TLC. Any help with valuing would be much appreciated as need to get them on the market asap. Cheers
