People4charity, a branch of people4business, lists freelances and contractor support workers in the areas most sought after by charities.
There are 6,800 professionals on the database of whom 1,200 offer discounts of between five and 85 per cent, with an average of 15 per cent.
Sectors covered include administration, education and research, finance and accounting, human resources, IT and internet, training and development, legal services, management consultancy, marketing and PR and property and construction.
Registration is free for workers who advertise their rates, availability and charity discounts from a personal home page.
Charities can search the database for people they require by sector, skills, track record, location and price and a contract is agreed between the two parties.
People4charity takes a fixed 10 per cent commission from the seller’s chosen rate and returns five per cent of its profits to the voluntary sector.
Emma Wood, manager of people4charity, said: “Charities often need the support of professionals for projects just like commercial organizations, but what they also want is complete price transparency and, where possible, support from people who share their values.”
